(4) Clock timer
When the port-XC selection bit of the oscillation circuit control register
0 (refer to Figure 63) is set to “1” to make the sub-clock oscillation
circuit active, timer B2 can function as the clock timer, which uses
clock fC32 as the clock source. Clock fC32 is the sub clock (32 kHz)
divided by 32.
Additionally, when the port-Xc selection bit is set to “0” not to use the
sub-clock and the timer B2 clock source selection bit of the port
function control register (refer to Figure 11) is set to “1”, timer B2 can
functions as the clock timer, which uses clock fc32 as the clock source.
Clock fc32 is the main clock divided by 32.
Figure 35 shows the timer B2 mode register bit configuration when
timer B2 is used as the clock timer. As shown in Figure 35, the event
counter mode must be selected for timer B2.
For how to use the clock timer, refer to the section on clock generating
circuit.
(5) Internal connect mode
When the timer B1 internal connect selection bit of the port function
control register (refer to Figure 11) is set to “1”, timer B1 uses the
timer B2’s overflow signal as the clock source and timer B1 is internally
connected to timer B2 (cascade connection).
The internal connect mode makes timers B1 and B2 function as 16 +
16 bit-timer with the timer B2’s clock source.
Figure 35 shows the timer B1 mode register bit configuration when
using timer B1 in the internal connect mode. Set timer B1 in the event
counter mode as shown in Figure 35.
