Bit Name Reset R/W Description
7:0
T1CC3[15:8]
0x00 R/W Timer 1 channel 3 capture/compare value high-order byte. Writing to this register when
T1CCTL3.MODE = 1 (compare mode) causes the T1CC3[15:0] update to the written value to be
delayed until T1CNT = 0x0000.

Bit Name Reset R/W Description
7:0
T1CC3[7:0]
0x00 R/W Timer 1 channel 3 capture/compare value low-order byte. Data written to this register is stored in
a buffer but not written to T1CC3[7:0] until, and at the same time as, a later write to T1CC3H
takes effect.
