This LSI has four units (unit 0 to unit 3) of an on-chip 8-bit timer module that comprise two 8-bit
counter channels, totaling eight channels. The 8-bit timer module can be used to count external
events and also be used as a multifunction timer in a variety of applications, such as generation of
counter reset, interrupt requests, and pulse output with a desired duty cycle using a compare-match
signal with two registers.
Figures 16.1 to 16.4 show block diagrams of the 8-bit timer module (unit 0 to unit 3).
This section describes unit 0 (channels 0 and 1) and unit 2 (channels 4 and 5), both of which have
the same functions. Unit 2 and unit 3 can generate baud rate clock for SCI and have the same
functions.
16.1
• Selection of seven clock sources
• Selection of three ways to clear the counters
• Timer output control by a combination of two compare match signals
• Cascading of two channels
• Three interrupt sources
• Generation of trigger to start A/D converter conversion (available in unit 0 to unit 3).
• Capable of generating baud rate clock for SCI_5 and SCI_6. (This is available only in unit 2
• Module stop state specifiable
The counters can be driven by one of six internal clock signals (Pφ/2, Pφ/8, Pφ/32, Pφ/64,
Pφ/1024, or Pφ/8192) or an external clock input (only internal clock available in units 2 and 3:
Pφ, Pφ/2, Pφ/8, Pφ/32, Pφ/64, Pφ/1024, and Pφ/8192).
The counters can be cleared on compare match A or B, or by an external reset signal. (This is
available only in unit 0 and unit 1.)
The timer output signal in each channel is controlled by a combination of two independent
compare match signals, enabling the timer to output pulses with a desired duty cycle or PWM
output.
Operation as a 16-bit timer is possible, using TMR_0 for the upper 8 bits and TMR_1 for the
lower 8 bits (16-bit count mode).
TMR_1 can be used to count TMR_0 compare matches (compare match count mode).
Compare match A, compare match B, and overflow interrupts can be requested independently.
(This is available only in unit 0 and unit 1.)
and unit 3). For details, see section 19, Serial Communication Interface (SCI, IrDA, CRC).
