Freescale Semiconductor
The following codes are relevant for FlashMedia command register 2:
FLASHMEDIACMD2[23:16] = 0x46: Send read data command to SD.
(drive cmd line after receiving flash status, do not drive data lines)
FLASHMEDIACMD2[23:16] = 0x40: Receive status for read data command from SD
FLASHMEDIACMD2[23:16] = 0xC6: Send write data command to SD.
(Drive cmd line after receiving flash status. Drive data line after sending command.)
FLASHMEDIACMD2[23:16] = 0xC0: Receive status for write data command from SD
FLASHMEDIACMD2[23:16] = 0x06: Send non-data command to SD
FLASHMEDIACMD2[23:16] = 0x00: Receive status for non-data command, stop driving cmd and data lines.
