12.2 16-bit Timer/Counter Mode
The Timer register is being run with 16 bits. A 16-bit timer/
counter register T0, T1 are increased from 0000
H
until it
matches TDR0, TDR1 and then resets to 0000
H
. The
match output generates Timer 0 interrupt not Timer 1 in-
terrupt.
The clock source of the Timer 0 is selected either internal
or external clock by bit T0CK2, T0CK1 and T0SL0.
In 16-bit mode, the bits T1CK1,T1CK0 and 16BIT of TM1
should be set to “1” respectively.

12.3 8-bit Compare Output (16-bit)
The HMS87C1304A and HMS87C1302A has a function
of Timer Compare Output. To pulse out, the timer match
can goes to port pin(COMP0) as shown in Figure 12-2 and
Figure 12-5 . Thus, pulse out is generated by the timer
match. These operation is implemented to pin, RB4/
COMP0/PWM.
This pin output the signal having a 50: 50 duty square
wave, and output frequency is same as below equation.
In this mode, the bit PWMO of RB function register (RB-
FUNC) should be set to “1”, and the bit PWME of timer1
mode register (TM1) should be set to “0”.
In addition, 16-bit Compare output mode is available, also.
12.4 8-bit Capture Mode
The Timer 0 capture mode is set by bit CAP0 of timer
mode register TM0 (bit CAP1 of timer mode register TM1
for Timer 1) as shown in Figure 12-6 .
As mentioned above, not only Timer 0 but Timer 1 can also
be used as a capture mode.
The Timer/Counter register is increased in response inter-
nal or external input. This counting function is same with
normal timer mode, and Timer interrupt is generated when
