Generic Description
Name
EMR External Match Register. The EMR controls the
external match pins MAT2.2..0 and MAT3.3..0.
Note: MAT2.3 is not connected to a pin on
LPC2101/02/03.
CTCR Count Control Register. The CTCR selects between
Timer and Counter mode, and in Counter mode
selects the signal and edge(s) for counting.
PWMCON PWM Control Register. The PWMCON enables
PWM mode for the external match pins MAT2.3..0
and MAT3.3..0.

16.5.1 Interrupt Register (IR TIMER2: T2IR - 0xE007 0000 and TIMER3: T3IR -
0xE007 4000)
The Interrupt Register consists of four bits for the match interrupts and four bits for the
capture interrupts. If an interrupt is generated then the corresponding bit in the IR will be
HIGH. Otherwise, the bit will be LOW. Writing a logic one to the corresponding IR bit will
reset the interrupt. Writing a zero has no effect.
