(8) Internal high-speed oscillator trimming register (HIOTRM)
154
This register is used to adjust the accuracy of the internal high-speed oscillator.
With self-measurement of the internal high-speed oscillator frequency via a subsystem clock using a crystal
resonator, a timer using high-accuracy external clock input (real-time counter or timer array unit), and so on, the
register can adjust the accuracy.
HIOTRM can be set by an 8-bit memory manipulation instruction.
Reset signal generation sets this register to 10H.
Caution The frequency will vary if the temperature and V
Moreover, if the HIOTRM register is set to any value other than the initial value (10H), the
oscillation accuracy of the internal high-speed oscillation clock may exceed 8 MHz±5%,
depending on the subsequent temperature and V
When the temperature and V
or before the frequency accuracy is required.
