Description
Number of bytes to be transferred; should be integer multiple
of Block Size for block transfers. For undefined number of byte
transfers, byte count should be set to 0. When byte count is set
to 0, it is responsibility of host to explicitly send stop/abort
command to terminate data transfer.
Description
One bit per card indicates if card is 1-bit or 4-bit:
0 - 1-bit mode
1 - 4-bit mode Bit[15] corresponds to card[15], bit[0]
corresponds to card[0]. Only NUM_CARDS*2 number of bits
are implemented.
One bit per card indicates if card is 8-bit:
0 - Non 8-bit mode
1 - 8-bit mode Bit[31] corresponds to card[15]; bit[16]
corresponds to card[0].
Description
Card detect. Bits used to mask unwanted interrupts. Value
of 0 masks interrupt; value of 1 enables interrupt.
Response error. Bits used to mask unwanted interrupts.
Value of 0 masks interrupt; value of 1 enables interrupt.
Command done. Bits used to mask unwanted interrupts.
Value of 0 masks interrupt; value of 1 enables interrupt.
Data transfer over. Bits used to mask unwanted interrupts.
Value of 0 masks interrupt; value of 1 enables interrupt.
Transmit FIFO data request. Bits used to mask unwanted
interrupts. Value of 0 masks interrupt; value of 1 enables
interrupt.
