Chapter 20: LPC1100/LPC1100C/LPC1100L series: 32-bit counter/timer
20.7.7 Match Registers (TMR32B0MR0/1/2/3 - addresses 0x4001
4018/1C/20/24 and TMR32B1MR0/1/2/3 addresses 0x4001
8018/1C/20/24)
The Match register values are continuously compared to the Timer Counter value. When
the two values are equal, actions can be triggered automatically. The action possibilities
are to generate an interrupt, reset the Timer Counter, or stop the timer. Actions are
controlled by the settings in the MCR register.
20.7.8 Capture Control Register (TMR32B0CCR and TMR32B1CCR)
The Capture Control Register is used to control whether the Capture Register is loaded
with the value in the Timer Counter when the capture event occurs, and whether an
interrupt is generated by the capture event. Setting both the rising and falling bits at the
same time is a valid configuration, resulting in a capture event for both edges. In the
description below, “n” represents the Timer number, 0 or 1.
9 MR3I Interrupt on MR3: an interrupt is generated when MR3 matches the value in the TC. 0
1 Enabled
0 Disabled
10 MR3R Reset on MR3: the TC will be reset if MR3 matches it. 0
1 Enabled
0 Disabled
11 MR3S Stop on MR3: the TC and PC will be stopped and TCR[0] will be set to 0 if MR3 matches
the TC.
