Hardware Functional Description
7.4.5.2.13
SSI Option Register (SOR)
Figure 65. SOR Register Diagram
RFDIR—Receive Frame Direction
This control bit selects the direction and source of the receive frame sync signal.
1 = Receive frame sync
is generated internally and output to the SRFS pin.
0 = Receive frame sync is external, meaning that the receive frame sync is supplied from an external
source.
TFDIR—Transmit Frame Direction
This control bit selects the direction and source of the transmit frame sync signal.
1 = Transmit frame sync
is generated internally and output to the STFS pin.
0 = Transmit frame sync is external, meaning that the transmit frame sync is supplied from an
external source.
INIT—Initialize State Machine
This bit is used to initialize the state machine to reset state.
1 = Reset the TX and RX state machines.
Setting this bit must be followed by a write of zero before the state machine with operate.
0 = State machine is allowed to operate.
WAIT[1:0]—Wait State
This bit field controls the number of wait states to be added to the transaction between the CPU and SSI.
The MC72000 does not use wait states and as such these should always be written 0.
SYNRST—Frame Sync Reset
1 = Resets the accumulation of data in SRX and RXFIFO on frame synchronization.
0 = Data must be read to be cleared from the registers.
