2–3
DCONF
[0:1]
DSPI configuration. Selects between the three different configurations of the DSPI. The following table lists
the DCONF values for the various configurations.
4
FRZ
Freeze. Enables the DSPI transfers to be stopped on the next frame boundary when the device enters debug
mode.
0 Do not halt serial transfers
1 Halt serial transfers
5
MTFE
Modified timing format enable. Enables a modified transfer format to be used. Refer to
“Modified SPI/DSI Transfer Format (MTFE = 1, CPHA = 1)
,” for more information.
0 Modified SPI transfer format disabled
1 Modified SPI transfer format enabled
6
PCSSE
Peripheral chip select strobe enable. Enables the PCS
x
[5] / PCSS to operate as a PCS strobe output signal.
Refer to
Section 19.4.6.5, “Peripheral Chip Select Strobe Enable (PCSS)
,” for more information.
0 PCS
x
[5] / PCSS is used as the Peripheral chip select 5 signal
1 PCS
x
[5] / PCSS is used as an active-low PCS strobe signal
7
ROOE
Receive FIFO overflow overwrite enable. Enables an RX FIFO overflow condition to ignore the incoming
serial data or to overwrite existing data. If the RX FIFO is full and new data is received, the data from the
transfer that generated the overflow is ignored or put in the shift register.
If the ROOE bit is set, the incoming data is put in the shift register. If the ROOE bit is cleared, the incoming
data is ignored. Refer to
Section 19.4.9.6, “Receive FIFO Overflow Interrupt Request (RFOF)
,” for more
information.
0 Incoming data is ignored
1 Incoming data is put in the shift register
8–9
Reserved, but implemented. These bits are writable, but have no effect.
10–15
PCSIS
n
Peripheral chip select inactive state. Determines the inactive state of the PCS
xn
signal. PCS
x
[0] / SS must
be configured as inactive high for slave mode operation.
0 The inactive state of PCS
xn
is low
1 The inactive state of PCS
xn
is high
16
Reserved.
