Detailed Description

Macro Definition Documentation

#define FPGA_check_faults ( ) MLC_READ(FPGA_FAULTS_ADDR)

Macro for reading FAULT inputs from converters.

Definition at line 506 of file MLC_drv.h.

#define MLC_READ ( addr ) *((volatile uint16_t*)BASE_ADDRESS+addr)

Macro for reading from XINTF/EMIF connected peripherals.

Parameters

addr	address of external peripheral, use defined constants READ_*

Returns: read from peripheral

Definition at line 486 of file MLC_drv.h.

Referenced by MLC_ADC_read(), and MLC_init().

#define MLC_WRITE	(	addr,
		data
	)	((volatile uint16_t)BASE_ADDRESS+addr)=(uint16_t)(data)

Macro for writing to XINTF/EMIF connected peripherals. CAUTION ! Macro casts it's data parameter to UNSIGNED INT of 16b wide. If design requires writing of SIGNED INT, then data can be UNSIGNED INT without problem, however automatic cast from other data types (i.e. float) will not work. They will be always positive.

Parameters

addr	uint16_t address of external peripheral, use defined constants WRITE_*
data	uint16_t data to write to peripheral

#define NO_FAULTS 0x3F

Constant defining value returned by FPGA_check_faults() when no FAULT is active.

void MLC_DBG_clear ( uint16_t dbg )

Clear debug outputs according to ones in dbg parameter.

Parameters

dbg	defines which debug outputs should be set to 0. I.e. passing 0x01 will turn off debug LED V1.

Definition at line 1791 of file MLC_drv.c.

References MLC_WRITE, and WRITE_DBGLEDS.

void MLC_DBG_set ( uint16_t dbg )

Set debug outputs according to ones in dbg parameter.

Parameters

dbg	defines which debug outputs should be set to 1. I.e. passing 0x01 will turn on debug LED V1.

Definition at line 1785 of file MLC_drv.c.

References MLC_WRITE, and WRITE_DBGLEDS.

void MLC_global_disable ( )

Use GPIO60 to disable CPLD and FPGA functionality. Useful for detecting DSP reset via JTAG. Requires CPLD firmware at least 0.4

Definition at line 872 of file MLC_drv.c.

References mlc_info_t::cpld_fw_ver.

void MLC_global_enable ( )

Use GPIO60 to enable CPLD and FPGA functionality. Useful for detecting DSP reset via JTAG. Requires CPLD firmware at least 0.4

Definition at line 855 of file MLC_drv.c.

References mlc_info_t::cpld_fw_ver.

void MLC_init ( )

This function should be called first, it initializes XINTF ZONE0, ZONE7 (if ext. RAM is used) and fixed purpose GPIOs.

Definition at line 824 of file MLC_drv.c.

Here is the call graph for this function:

void MLC_PWR_off ( uint16_t pwr )

Turn off PWR outputs according to ones in pwr parameter.

Parameters

pwr	defines which outputs should be turn off, in fact this means, that output will be floating, because those power outputs are open collector so turn off means disconnect from ground.

Definition at line 1779 of file MLC_drv.c.

References MLC_WRITE, and WRITE_PWR_OUT.

void MLC_PWR_on ( uint16_t pwr )

Turn on PWR outputs according to ones in pwr parameter.

Parameters

pwr	defines which outputs should be turn on, in fact this means, that output will be zero level. But those power outputs are open collector so turn on means connect to ground.

Definition at line 1773 of file MLC_drv.c.

References MLC_WRITE, and WRITE_PWR_OUT.

__inline uint16_t MLC_read ( uint16_t addr )

Function for reading from XINTF connected peripherals. However using macro MLC_READ() is recommended due higher performance.

Parameters

addr	address of external peripheral, use defined constants READ_*

Returns: value from periheral

Definition at line 501 of file MLC_drv.h.

References BASE_ADDRESS.

__inline void MLC_write	(	uint16_t	addr,
		uint16_t	data
	)

Function for writing to XINTF connected peripherals. However using macro MLC_WRITE() is recommended due higher performance.

Parameters

addr	address of external peripheral, use defined constants WRITE_*
data	data to write to periheral

Definition at line 495 of file MLC_drv.h.

References BASE_ADDRESS.
