T4CCTL1 (0xEE) – Timer 4 Channel 1 Capture/Compare Control
Bit Name Reset R/W Description
7 – 0 R0 Reserved
6
IM
1 R/W Channel 1 interrupt mask
5:3
CMP[2:0]
000 R/W Channel 1 compare output-mode select. Specified action on output when timer value equals
compare value in T4CC1
000: Set output on compare
001: Clear output on compare
010: Toggle output on compare
011: Set on compare-up, clear on compare-down in up-down mode. Otherwise, set output on
compare, clear on 0.
100: Clear output on compare-up, set on compare-down in up-down mode. Otherwise clear
output on compare, set on 0.
101: Set output on compare, clear on 0xFF
110: Clear output on compare, set on 0x00
111: Initialize output pin. CMP[2:0] is not changed.

MODE
0 R/W Mode. Select Timer 4 channel 1 mode
0: Capture mode
1: Compare mode
1:0
CAP[1:0]
00 R/W Capture mode select. 00 – No Capture, 01 – Capture on rising edge, 10 – Capture on falling
edge, 11 – Capture on both edges
T4CC1 (0xEF) – Timer 4 Channel 1 Capture/Compare Value
Bit Name Reset R/W Description
7:0
VAL[7:0]
0x00 R/W Timer capture/compare value, channel 1. Writing to this register when T4CCTL1.MODE = 1
(compare mode) causes the T4CC1.VAL[7:0] update to the written value to be delayed until
T4CNT.CNT[7:0] = 0x00.
