10.2.2 CSIn control registers
CSIn is controlled by the following registers.
•
Serial operation mode register n (CSIMn)
•
Serial clock selection register n (CSISn)
(1) Serial clock selection registers 0 to 3 (CSIS0 to CSIS3) and serial operation mode registers 0 to 3 (CSIM0
to CSIM3)
The CSISn register is used to set serial interface channel n’s serial clock.
The CSISn register can be set by an 8-bit memory manipulation instruction.
RESET input clears the CSISn register to 00H.
The CSIMn register is used to enable or disable serial interface channel n’s serial clock, operation modes, and
specific operations.
The CSIMn register can be set by an 8-bit or 1-bit memory manipulation instruction.
RESET input clears the CSIMn register to 00H.
