8-bit microcontrollers with 80C51 core
6.9 PCA
The PCA includes a special 16-bit Timer that has ve 16-bit capture/compare modules
associated with it. Each of the modules can be programmed to operate in one of four
modes: rising and/or falling edge capture, software timer, high-speed output, or PWM.
Each module has a pin associated with it in port 1. Module 0 is connected to P1.3 (CEX0),
module 1 to P1.4 (CEX1), etc. Registers CH and CL contain current value of the free
running up counting 16-bit PCA timer. The PCA timer is a common time base for all ve
modules and can be programmed to run at: 1
6 the oscillator frequency,
1
2 the oscillator
frequency, the Timer 0 overow, or the input on the ECI pin (P1.2). The timer count source
is determined from the CPS1 and CPS0 bits in the CMOD SFR (see Table 35 and
Table 33.

WDOUT
Watchdog output enable. When this bit and WDRE are both set, a
Watchdog reset will drive the reset pin active for 32 clocks.
3
WDRE
Watchdog timer reset enable. When set enables a watchdog timer
reset.
2
WDTS
Watchdog timer reset ag, when set indicates that a WDT reset
occurred. Reset in software.
1
WDT
Watchdog timer refresh. Set by software to force a WDT reset.
0
SWDT
Start watchdog timer, when set starts the WDT. When cleared, stops
the WDT.
