TIMER B
Figure 27 shows a block diagram of timer B.
Timer B has three modes; timer mode, event counter mode, and
pulse period measurement/pulse width measurement mode. The
mode is selected with bits 0 and 1 of the timer Bi mode register
(i = 0 to 2). Each of these modes is described below.
(1) Timer mode [00]
Figure 28 shows the bit configuration of the timer Bi mode register
during timer mode. Bits 0, and 1 of the timer Bi mode register must
always be “0” in timer mode.
Bits 6 and 7 are used to select the clock source. The counting of
the selected clock starts when the count start flag is “1” and stops
when “0”.
As shown in Figure 13, the timer Bi count start flag is at the same
address as the timer Ai count start flag. The count is decremented,
an interrupt occurs, and the interrupt request bit in the timer Bi in-
terrupt control register is set when the contents becomes 000016.
At the same time, the contents of the reload register is stored in
the counter and count is continued.
Timer Bi does not have a pulse output function or a gate function
like timer A.
When data is written to timer Bi halted, it is written to the reload
register and the counter. When data is written to timer Bi which is
busy, the data is written to the reload register, but not to the
counter. The counter is reloaded with new data from the reload
register at the next reload time. The contents of the counter can
be read at any time.
