Legend:
R = Readable bit
U = Unimplemented bit
W = Writable bit
P = Programmable bit
-n = Bit Value at POR: (‘0’, ‘1’, x = Unknown)
r = Reserved bit

bit 12-8
bit 7
bit 6-4
Reserved: Write ‘0’; ignore read
ON: Timer On bit
1 = Timer is enabled
0 = Timer is disabled
FRZ: Freeze in Debug Exception Mode bit
1 = Freeze operation when CPU is in Debug Exception mode
0 = Continue operation when CPU is in Debug Exception mode
Note: FRZ is writable in Debug Exception mode only, it is forced to ‘0’ in normal mode.
SIDL: Stop in Idle Mode bit
1 = Discontinue operation when device enters Idle mode
0 = Continue operation in Idle mode
Reserved: Write ‘0’; ignore read
TGATE: Gated Time Accumulation Enable bit
When TCS = 1:
This bit is ignored and read ‘0’.
When TCS = 0:
1 = Gated time accumulation is enabled
0 = Gated time accumulation is disabled
TCKPS<2:0>: Timer Input Clock prescaler Select bits
111 = 1:256 prescale value
110 = 1:64 prescale value
101 = 1:32 prescale value
100 = 1:16 prescale value
011 = 1:8 prescale value
010 = 1:4 prescale value
001 = 1:2 prescale value
000 = 1:1 prescale value
