Figure 14-3:
Queued CSI Clock Selection Registers (CSIC0, CSIC1) Format (2/2)
Note:
SCK3 pin is configured as input mode for serial transfer clock.
f
QCSI
is the clock supply of the Queued-CSI macro.
Caution:
Rewriting these bits is only permitted when CSIE = 0.
See sections
14.3.4 ”Slave Mode” on page 479
and
14.3.5 ”Master Mode” on page 479
for
further explanation on slave mode and master mode.
Caution:
Rewriting these bits is only permitted when CTXE = 0 and CRXE = 0.
MDL [2:0] = [0,0,1] is prohibited when CKS [2:0] = [0,0,0].
See section
14.3.6 ”Transmission Clock Select Function” on page 480
for further explanation
on the transfer clock selection.
