SHIFTCTL(n+1)
0x0000_0101
Configure receive using Timer 0 on
posedge of clock with input data on Pin
1.
TIMCMPn
0x0000_3F01
Configure 32-bit transfer with baud rate
of divide by 4 of the FlexIO clock. Set
TIMCMP[15:8] = (number of bits x 2) - 1.
Set TIMCMP[7:0] = (baud rate divider /
2) - 1.
TIMCFGn
0x0100_2222
Configure start bit, stop bit, enable on
trigger high and disable on compare,
initial clock state is logic 0. Set PINPOL
to invert the output shift clock.
TIMCTLn
0x01C3_0201
Configure dual 8-bit counter using Pin 2
output (shift clock), with Shifter 0 flag as
the inverted trigger.
TIMCMP(n+1)
0x0000_FFFF
Never compare.
TIMCFG(n+1)
0x0000_1100
Enable when Timer 0 is enabled and
disable when Timer 0 is disabled.
TIMCTL(n+1)
0x0003_0383
Configure 16-bit counter (never
compare) using inverted Pin 3 output (as
slave select).
SHIFTBUFn
Data to transmit
Transmit data can be written to
SHIFTBUF, use the Shifter Status Flag
to indicate when data can be written
using interrupt or DMA request. Can
support MSB first transfer by writing to
SHIFTBUFBBS register instead.
SHIFTBUF(n+1)
Data to receive
Received data can be read from
SHIFTBUFBYS, use the Shifter Status
Flag to indicate when data can be read
using interrupt or DMA request. Can
support MSB first transfer by reading
from SHIFTBUFBIS register instead.

SHIFTCFGn
0x0000_0021
Start bit loads data on first shift.
SHIFTCTLn
0x0003_0002
Configure transmit using Timer 0 on
posedge of clock with output data on Pin
0.
SHIFTCFG(n+1)
0x0000_0000
Start and stop bit disabled.
SHIFTCTL(n+1)
0x0080_0101
Configure receive using Timer 0 on
negedge of clock with input data on Pin
1.
TIMCMPn
0x0000_3F01
Configure 32-bit transfer with baud rate
of divide by 4 of the FlexIO clock. Set
TIMCMP[15:8] = (number of bits x 2) - 1.
