Programmable Clock-Out
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:
1.
to input the external clock for Timer/Counter 2, or
2.
to output a 50% duty cycle clock ranging from 122 Hz to 8 MHz at a 16 MHz operating fre-
quency (61 Hz to 4 MHz in 12 clock mode).
To configure Timer/Counter 2 as a clock generator, bit C/#T2 (in T2CON) must be cleared and bit T20E
in T2MOD must be set. Bit TR2 (T2CON.2) also must be set to start the timer.
The Clock-Out frequency depends on the oscillator frequency and the reload value of Timer 2 capture
registers (RCAP2H, RCAP2L) as shown in this equation:
Oscillator Frequency
n x (65536 - RCAP2H, RCAP2L)
n = 2 (in 6 clock mode)
4 (in 12 clock mode)
Where (RCAP2H, RCAP2L) = the contents of RCAP2H and RCAP2L taken as a 16-bit unsigned inte-
ger.
In the Clock-Out mode, Timer 2 roll-overs will not generate an interrupt. This is similar to when it is
used as a baud-rate generator. It is possible to use Timer 2 as a baud-rate generator and a clock gen-
erator simultaneously. Note, however, that the baud-rate and the Clock-Out frequency will not be the
same.
