Receive Data Buffer Register A[3:0] = 0100, Read only, 8-bit data size:
When the extraction of the TPC code is READ_PAGE_DATA or READ_REG or GET_INT, the data
received from the SDIO pin and is recorded in receive data buffer, the RBE and RBF bits in the status
register will reflect the buffer status and XDRQN will active. The received data can be read out by
reading this register repeatedly until receive buffer is empty. Only high byte data (bit[15:8]) is valid if
the last data is one byte only.
The data is located at bit[7:0] and address bit 0 must set 0 when read the receive data buffer register
with 8-bit data size of Host CPU.
Transmit Data Buffer Register A[3:1] = 010, Write only:
Transmit Data Buffer Register A[3:0] = 0100, Write only, 8-bit data size:
When
SET_R/W_REG_ADDRESS or SET_CMD. The data stored in the transmit data buffer will transmitted
to the SDIO pin, the TBE and TBF bits in the status register will reflect the transmit buffer status and
XDRQN will active when the buffer is not full and the data size is not enough. The transmit data must
be written to this register repeatedly until the data size specified in the command register is enough.
Only high byte data (bit[15:8]) is valid if the last data is one byte only.
The data is located at bit[7:0] and address bit 0 must set 0 when write the transmit data buffer register
with 8-bit data size of Host CPU.
