8.3 Configuration
TMQ0 includes the following hardware.
Table 8-1. Configuration of TMQ0
Item Configuration
Timer register 16-bit counter
Registers
TMQ0 capture/compare registers 0 to 3 (TQ0CCR0 to TQ0CCR3)
TMQ0 counter read buffer register (TQ0CNT)
CCR0 to CCR3 buffer registers
Timer inputs 4 (TIQ00
Note 1
to TIQ03 pins)
Timer outputs 4 (TOQ00 to TOQ03 pins)
Control registers
Note 2
TMQ0 control registers 0, 1 (TQ0CTL0, TQ0CTL1)
TMQ0 I/O control registers 0 to 2 (TQ0IOC0 to TQ0IOC2)
TMQ0 option register 0 (TQ0OPT0)
Notes 1. The TIQ00 pin functions alternately as a capture trigger input signal, external event count input
signal, and external trigger input signal.
2. When using the functions of the TIQ00 to TIQ03 and TOQ00 to TOQ03 pins, see Table 4-15 Using
Port Pin as Alternate-Function Pin.
