8-bit Timer/Counter0 with PWM
Timer/Counter0 is a general purpose 8-bit Timer/Counter module, with two independent Output Compare Units, and with PWM
support. It allows accurate program execution timing (event management) and wave generation. The main features are:
●
Two independent output compare units
●
Double buffered output compare registers
●
Clear timer on compare match (auto reload)
●
Glitch free, phase correct pulse width modulator (PWM)
●
Variable PWM period
●
Frequency generator
●
Three independent interrupt sources (TOV0, OCF0A, and OCF0B)
12.1
Overview
A simplified block diagram of the 8-bit Timer/Counter is shown in Figure 12-1. For the actual placement of I/O pins, refer to
Section 2.3 “Pin Descriptions” on page 9. CPU accessible I/O registers, including I/O bits and I/O pins, are shown in bold. The
device-specific I/O Register and bit locations are listed in Section 12.8 “8-bit Timer/Counter Register Description” on page 86.
The PRTIM0 bit in Section 6.6 “Power Reduction Register” on page 36 must be written to zero to enable Timer/Counter0
module.
