Three external interrupts.
Two from T8, T16 time-out and capture.
Three from UART Tx, UART Rx, and UART BRG.
One from LVD.
Fourteen from SMR source P20-P27, P30-P33, P00, and P07:
–
IR learning amplifier.
Low power consumption—11 mW (typical).
Three standby modes:
–
–
–
Intelligent counter/timer architecture to automate generation or reception and
demodulation of complex waveform, and pulsed signals:
–
–
–
–
Six priority interrupts:
–
–
–
Any change in logic from P20-P27, P30-P33 can generate an interrupt or SMR
STOP—1.7 A (typical)
HALT—0.6 mA (typical)
Low-voltage reset
One programmable 8-bit counter/timer with two capture registers and two
load registers
One programmable 16-bit counter/timer with one 16-bit capture register pair
and one 16-bit load register pair
Programmable input glitch filter for pulse reception
The UART baud rate generator can be used as another 8-bit timer, when the
UART is not in use
Three external/UART interrupts
Two assigned to counter/timers
One low-voltage detection interrupt
