12.1 8-bit Timer / Counter Mode
The HMS81C20xxA has two 8-bit Timer/Counters, Timer
0, Timer 1 as shown in Figure 12-2.
The "timer" or "counter" function is selected by mode reg-
isters TMx as shown in Figure 12-1 and Table 12-1. To use
as an 8-bit timer/counter mode, bit CAP0 of TM0 is
cleared to "0" and bits 16BIT of TM1 should be cleared to
“0”(Table 12-1).
