5. Function Description
5.2 System Clock
The S1V3S344 system clock frequency can be set to either 32.768 kHz or 12.288 MHz. The clock source can be
set to be either direct input (input from CLKI pin) or oscillator (connected to OSCI/OSCO pin). The oscillator,
however, can be used with 32.768 kHz only. The frequency and clock source settings are defined by the input pin
CLKSEL and OSCEN settings. Table 5.1 shows system clock mode settings.
