12.1 8-bit Timer/Counter Mode
The HMS87C1304A and HMS87C1302A has four 8-bit
y ^{Timer/Counters, Timer 0 and Timer 1 as shown in Figure}
r ^{12-2 .}
a ^{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 ).
