1. This bit is the bit4 of RB Function register(RBFUNC).
2. X : The value is “0” or “1” corresponding your operation.
16.1 8-bit Timer/Counter Mode
The GMS81C1202 has two 8-bit Timer/Counters, Timer 0
and Timer 1, as shown in Figure 16-2 .
The "timer" or "counter" function is selected by mode reg-
isters TM0, TM1 as shown in Figure 16-1 and Table 16-1
. 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 16-1).
