16-Bit Microcontroller with Infrared Module
MAXQ61C
______________________________________________________________________________________ 17
16-Bit Timers/Counters
The microcontroller provides two timers/counters that
support the following functions:
16-bit timer/counter
16-bit up/down autoreload
Counter function of external pulse
16-bit timer with capture
16-bit timer with compare
Input/output enhancements for pulse-width modulation
Set/reset/toggle output state on comparator match
Prescaler with 2n divider (for n = 0, 2, 4, 6, 8, 10)

CARRIER FREQUENCY
CALCULATION
IRRX
IRV
IRMT
IRMT = PULSE COUNTING
IRV = CARRIER CYCLE COUNTING
CAPTURE INTERRUPT (IRIF = 1).
IRV
≥ IRMT.
IRV = 0 (IF IRXRL = 1).
SOFTWARE SETS IRCA = CARRIER FREQUENCY.
SOFTWARE SETS RXBCNT = 1 (WHICH CLEARS IRMT = 0001 IN HARDWARE).
SOFTWARE CLEARS IRCFME = 0 SO THAT IRV COUNTS CARRIER CYCLES. IRV IS RESET TO 0 ON QUALIFIED EDGE DETECTION IF IRXRL = 1.
SOFTWARE ADDS TO IRMT THE NUMBER OF PULSES USED FOR CARRIER MEASUREMENT.
IRCA x 2x COUNTER FOR SPACE CAN BEGIN IMMEDIATELY (QUALIFIED EDGE RESETS).
QUALIFIED EDGE DETECTED: IRMT++
IRV RESET TO 0 IF IRXRL = 1.
IRCA x 2 PERIOD ELAPSES: IRIF = 1; CARRIER ABSENCE = SPACE.
BURST MARK = IRMT PULSES.
SOFTWARE CLEARS RXBCNT = 0 SO THAT WE CAPTURE ON THE NEXT QUALIFIED EDGE.
QUALIFIED EDGE DETECTED: IRIF = 1, CAPTURE IRV IRMT AS THE BURST SPACE (PLUS UP TO ONE CARRIER CYCLE).
SOFTWARE SET RXBCNT = 1 AS IN (5).
CONTINUE (5) TO (8) UNTIL LEARNING SPACE EXCEEDS SOME DURATION. IRV ROLLOVERS CAN BE USED.
