Preliminary
MATRA MHS
Programmable Clock Output
A 50% duty cycle clock can be programmed to come out on P1.0. This pin, besides being a regular I/O pin, has two
alternate functions. It can be programmed to input external clock for Timer/Counter 2 or to output a 50% duty cycle
clock from frequency fosc/2
18
to frequency fosc/4 (61 Hz to 4 MHz at a 16 MHz operating frequency).
The clock–out frequency depends on the oscillator frequency and the reload value of Timer 2 capture registers
RCAP2H and RCAP2L as shown in this equation:
Oscillator frequency
Clock–Out frequency=4
(65536 – RCAP2H,RCAP2L)
To configure the Timer/Counter 2 as a clock generator, bit C/T2 in T2CON (bit location 1) must be cleared and bit T2OE
must be set. Bit TR2 in T2CON starts and stops the timer (see Figure 7). T2OE is located in T2MOD at bit location
1 (see Table 5).
In the clock–out mode, Timer 2 roll–overs will not generate an interrupt. This is similar to when Timer 2 is used as
a baud–rate generator. It is possible to use Timer 2 as a baud–rate generator and as clock generator simultaneously.
Note however, that the baud–rate and clock–out frequencies can not be determined independently from one another
since they both use RCAP2H and RCAP2L.
