NOTE)
1. The system clock is not disabled by the corresponding bit of the OSCCR register. Ex) The high
frequency internal RC oscillator won’t be disabled by the HFIRCE bit during the fHFIRC is selected as
the system clock.
LIFSR (LFIRC Frequency Selection Register): C9H
Initial value: 00H
Write Identification bits. These bits are automatically cleared to “00000b” immediately
after LIWTP write. 0x00 on read.
Write 0x16 to these bits with valid LFIRCS[1:0]
LFIRC oscillator post-divider selection.
