Timer B1 is an 8-bit timer that increments each time a clock pulse is input. This timer has two
operation modes, interval and auto reload.
Features
Features of timer B1 are given below.
Choice of seven internal clock sources ( /8192, /2048, /512, /256, /64, /16, /4) or an
external clock (can be used to count external events).
An interrupt is requested when the counter overflows.

active mode or sleep mode, the internal clock is not synchronous with the system clock, so
it is synchronized by a synchronizing circuit. This may result in a maximum error of 1/ (s) in
the count cycle.
