Each of the modules. Each module has a pin associated with it in port 1. Module 0 is connected to P1.

The PCA timer is a common time base for all five modules and can. The timer count source is determined from the CPS1 and. WDTE which enables or disables the watchdog function on. These functions are shown in Figure The watchdog timer function is implemented in module 4 see.

PCA is shut off by clearing this bit. Bits 0 through 4 of the CCON register are the flags for.

The PCA interrupt system. Each module in the PCA has a special function register associated. The registers contain the bits that.

If both bits are set both edges will be enabled and a capture will. The last bit in the register ECOM.

There are two additional registers associated with each of the PCA. When a module is used in the PWM mode. Electronic Components Datasheet Search.

Part Name Included start with end match. Each of the modules can be programmed to operate in one of four modes: The basic PCA configuration is shown in Figure The PCA timer is a common time base for all five modules and can be programmed to run at: The watchdog timer function is fatasheet in module 4 see Figure The PCA is shut off by clearing this bit. Bits 0 through 4 of the CCON register are 89c51rf2 flags for the modules bit 0 for module 0, bit 1 for module 1, etc. These flags also can only be cleared by software.

The PCA interrupt system shown in Figure Each module in the PCA has a special function register associated with it. The registers contain the bits that control the mode that each module will operate in. If both bits are set both edges will be enabled and a capture will occur for either transition.

There are two additional registers associated with each of the PCA modules. When a module is used in the PWM mode these registers are used to control the duty cycle of the output.
