25.7.2 Timer control registers
25.7.3 Timer counter registers
25.7.4 Timer prescale registers
Table 534. Timer interrupt registers IR(IR - addresses 0x4008 4000 (TIMER0), 0x4008 5000
The Timer Control Register (TCR) is used to control the operation of the Timer/Counter.
Table 535. Timer control register TCR (TCR - addresses 0x4008 4004 (TIMER0), 0x4008 5004
The 32-bit Timer Counter register is incremented when the prescale counter reaches its
terminal count. Unless it is reset before reaching its upper limit, the Timer Counter will
count up through the value 0xFFFF FFFF and then wrap back to the value 0x0000 0000.
This event does not cause an interrupt, but a match register can be used to detect an
overflow if needed.
Table 536. Timer counter registers TC (TC - addresses 0x4008 4008 (TIMER0), 0x4008 5008
The 32-bit Timer prescale register specifies the maximum value for the Prescale Counter.

Description
Interrupt flag for capture channel 2 event.
Interrupt flag for capture channel 3 event.
Reserved.
Description
Timer counter value.
Description
Prescale counter maximum value.
Description
When one, the Timer Counter and Prescale Counter are
enabled for counting. When zero, the counters are
disabled.
When one, the Timer Counter and the Prescale Counter
are synchronously reset on the next positive edge of
PCLK. The counters remain reset until TCR[1] is
returned to zero.
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.
