Description

PSSI status register

Fields

RTT4B	FIFO is ready to transfer four bytes 0 (B_0x0): FIFO is not ready for a four-byte transfer 1 (B_0x1): FIFO is ready for a four-byte (32-bit) transfer. In receive mode, this means that at least four valid data bytes are in the FIFO. In transmit mode, this means that there are at least four bytes free in the FIFO.
RTT1B	FIFO is ready to transfer one byte 0 (B_0x0): FIFO is not ready for a 1-byte transfer 1 (B_0x1): FIFO is ready for a one byte (32-bit) transfer. In receive mode, this means that at least one valid data byte is in the FIFO. In transmit mode, this means that there is at least one byte free in the FIFO.
