CARD_ReadEeprom

Syntax

#include <nitro/card.h>

BOOL CARD_ReadEeprom(u32 src, void *dst, u32 len);

Arguments

src	Transfer source EEPROM address.
dst	Transfer destination memory address.
len	Length of data being read, in bytes.

Return Values

TRUE if the process succeeds. FALSE otherwise.

Description

This function reads data synchronously from an EEPROM device. The function does not return control until it has finished processing. It returns TRUE if the process was successful or FALSE if it failed. To get the value when processing fails, call the CARD_GetResultCode function. To use this function, you must first lock the access bus with the CARD_LockBackup function.

This function communicates with the ARM7 processor internally via PXI.
The process will not end if PXI interrupts are not enabled.
