User manual
6.3 PWM Count Control Register (PWM0CTCR - 0xE001 4070 and
6.4 PWM Match Control Register (PWM0MCR - 0xE001 4014 and
PWM1CTCR 0xE001 8070)
The Count Control Register (CTCR) is used to select between Timer and Counter mode,
and in Counter mode to select the pin and edge(s) for counting. The function of each of
the bits is shown in
Table 560: PWM Count control Register (PWM0TCR - address 0xE001 4004 and PWM1CTCR
[1]
PWM1MCR 0xE001 8014)
The PWM Match Control registers are used to control what operations are performed
when one of the PWM Match registers matches the PWM Timer Counter. The function of
each of the bits is shown in
Table 561: Match Control Register (PWM0MCR - address 0xE000 4014 and PWM1MCR -

PCAP input signal frequency must not exceed PCLK/4. When the PWM clock is supplied via the PCAP pin,
at no time high(low) level of the signal on this pin can last less than 1/(2

Description
00: Timer Mode: the TC is incremented when the
Prescale Counter matches the Prescale register.
01: Counter Mode: the TC is incremented on rising
edges of the PCAP input selected by bits 3:2.
10: Counter Mode: the TC is incremented on falling
edges of the PCAP input selected by bits 3:2.
11: Counter Mode: the TC is incremented on both edges
of the PCAP input selected by bits 3:2.
When bits 1:0 are not 00, these bits select which PCAP
pin carries the signal used to increment the TC.
For PWM0: 00 = PCAP0.0 (Other combinations are
reserved)
For PWM1: 00 = PCAP1.0, 01 = PCAP1.1(Other
combinations are reserved)
Reserved, user software should not write ones to
reserved bits. The value read from a reserved bit is not
defined.

Interrupt on PWMMR0: an interrupt is generated when
PWMMR0 matches the value in the PWMTC.
This interrupt is disabled.
Reset on PWMMR0: the PWMTC will be reset if PWMMR0
matches it.
This feature is disabled.
Stop on PWMMR0: the PWMTC and PWMPC will be stopped
and PWMTCR bt 0 will be set to 0 if PWMMR0 matches the
PWMTC.
This feature is disabled
