Time-base timer
The time-base timer is an 18-bit free-running counter (time-base timer counter) that counts in synchronization
with the main clock (2 cycles of the oscillation clock HCLK). Four different time intervals can be selected, for
each of which an interrupt request can be generated. Operating clock signals are supplied to peripheral resources
such as the oscillation stabilization wait timer and watchdog timer.
Interval time of time-base timer
Notes :
HCLK : Oscillation clock frequency
The parenthesized values assume an oscillator clock frequency of 6 MHz.
Clock cycles supplied from time-base timer
Notes :
HCLK : Oscillation clock frequency
