Section 14 Serial Communication Interface (SCI)
14.3.7
SSR is a register containing status flags of the SCI and multiprocessor bits for transfer. TDRE,
RDRF, ORER, PER, and FER can only be cleared. Some bits in SSR have different functions in
normal mode and smart card interface mode.

Description
Clock Enable 1, 0
These bits control the clock output from the SCK pin. In
GSM mode, clock output can be dynamically switched.
For details, see section 14.7.8, Clock Output Control.
