MFC2000 Multifunctional Peripheral Controller 2000

Hardware Description

15-4

Conexant

100723A

Bit1-0:

SASMode

Read/Write bits.

These two bits control the SASIF operation modes.

00: AsyncMode (default)

01: SyncMode

10 & 11: Reserved

Note: The TxFIFO enable and the RxFIFO enable should either be set or cleared once in the

setup of the SASIF device. Enabling or disabling the FIFOs once the MFC is up and running

could have unpredicted results if data is being received or sent by the shift registers.

Note: This is the Receive buffer data register. Reading from this register will return the data in

the Rxbuffer (for fifo disabled) or the oldest valid received data (for fifo enabled). However, after

a read, a write MUST be done to this register in order to let the SASIF know that data has been

read. This was done to help with emulation testing. Writing to the SASData Register will clear

the RxBufFull or RxFifoThresh status bits.

Note: This is the Transmit buffer data register. It is a write only register. Writing to this register

placed data into the transmit buffer register (or the transmit fifo if TxFifo is enabled). Writing to

the SASTxData Register will clear the TxBufEmpty or TxFifoThresh status bits.
