CKSTPR1 is an 8-bit read/write register that performs module standby mode control for peripheral
modules. Only the bits relating to SCI3 are described here. For details of the other bits, see the
sections on the relevant modules.
Bit 5—SCI3 Module Standby Mode Control (S32CKSTP)
Bit 5 controls setting and clearing of module standby mode for SCI3.
S32CKSTP Description
0
SCI3 is set to module standby mode^*
1
SCI3 module standby mode is cleared
Note: * All SCI3 register is initialized in module standby mode.
