BITS DESCRIPTIONS

[31:0]

Data Transmit Register

The I

C core used 32-bit transmit buffer and provide multi-byte

transmit function. Set CSR[Tx_NUM] to a value that you want to

transmit. I

C core will always issue a transfer from the highest byte

first. For example, if CSR[Tx_NUM] = 0x3, Tx[31:24] will be

transmitted first, then Tx[23:16], and so on.

In case of a data transfer, all bits will be treated as data.

In case of a slave address transfer, the first 7 bits will be treated as 7-

bit address and the LSB represent the R/W bit. In this case,

LSB = 1, reading from slave

LSB = 0, writing to slave
