default "128"
help
Allows the configuration of the timer frequency. It is customary
to have the timer interrupt run at 1000 Hz or 100 Hz, but in the
case of low timer frequencies other values may be more suitable.
SH-Mobile systems using a 32768 Hz RCLK for clock events may want
to select a HZ value such as 128 that can evenly divide RCLK.
A HZ value that does not divide evenly may cause timer drift.
