80C51 with 1 kB RAM, SPI
register is set. The CF bit can only be cleared by software. Bits 0 through 4 of the CCON
register are the ags for the modules (bit 0 for module 0, bit 1 for module 1, etc.) and are
set by hardware when either a match or a capture occurs. These ags can only be cleared
by software. All the modules share one interrupt vector. The PCA interrupt system is
shown in Figure 20.
Each module in the PCA has a special function register associated with it. These registers
are: CCAPM0 for module 0, CCAPM1 for module 1, etc. The registers contain the bits that
control the mode that each module will operate in.
The ECCF bit (from CCAPMn.0 where n = 0, 1, 2, 3, or 4 depending on the module)
enables the CCFn ag in the CCON SFR to generate an interrupt when a match or
compare occurs in the associated module; see Figure 20.
PWM (CCAPMn.1) enables the PWM mode.
The TOG bit (CCAPMn.2) when set causes the CEX output associated with the module to
toggle when there is a match between the PCA counter and the module’s
capture/compare register.
The match bit MAT (CCAPMn.3) when set will cause the CCFn bit in the CCON register to
be set when there is a match between the PCA counter and the module’s
capture/compare register.
The next two bits CAPN (CCAPMn.4) and CAPP (CCAPMn.5) determine the edge that a
capture input will be active on. The CAPN bit enables the negative edge, and the CAPP bit
enables the positive edge. If both bits are set both edges will be enabled and a capture will
occur for either transition.
The last bit in the register ECOM (CCAPMn.6) when set enables the comparator function.
There are two additional registers associated with each of the PCA modules. They are
CCAPnH and CCAPnL and these are the registers that store the 16-bit count when a
capture occurs or a compare should occur. When a module is used in the PWM mode,
these registers are used to control the duty cycle of the output.
