16.1
An on-chip 16-bit timer pulse unit (TPU) is provided that comprises three 16-bit timer channels.
16.1.1
The TPU has the following features:
Maximum 8-pulse input/output
A total of eight timer general registers (TGRs) are provided (four for channel 0 and two each
for channels 1, and 2).
Choice of seven or eight counter input clocks for each channel
The following operations can be set for each channel:
Buffer operation settable for channel 0
Phase counting mode settable independently for each of channels 1, and 2
Fast access via internal 16-bit bus
13 interrupt sources
Each register can be set independently as an output compare/input capture register.
TGRC and TGRD for channel 0 can be used as buffer registers
Waveform output by compare match: Selection of 0, 1, or toggle output
Input capture function: Choice of rising edge, falling edge, or both edge detection
Counter clear operation: Counter clearing possible by compare match or input capture
Synchronous operation: Multiple timer counters (TCNT) can be written to simultaneously
PWM mode: Any PWM output duty can be set maximum of 7-phase PWM output possible
Input capture register double-buffering possible
Automatic rewriting of output compare register possible
Two-phase encoder pulse up/down-count possible
Fast access is possible via a 16-bit bus interface
For channel 0 four compare match/input capture dual-function interrupts and one overflow
For channels 1, and 2, two compare match/input capture dual-function interrupts, one
simultaneous clearing by compare match and input capture possible
register simultaneous input/output possible by counter synchronous operation
by combination with synchronous operation
interrupt can be requested independently
overflow interrupt, and one underflow interrupt can be requested independently
