Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 15
TON: Timerx On bit
When T32 = 1:
1 = Starts 32-bit Timerx/y
0 = Stops 32-bit Timerx/y
When T32 = 0:
1 = Starts 16-bit Timerx
0 = Stops 16-bit Timerx
bit 14
Unimplemented: Read as ‘0’
bit 13
TSIDL: Timerx Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
bit 12-7
Unimplemented: Read as ‘0’

10 = 1:64
01 = 1:8 
00 = 1:1
bit 3
T32: 32-Bit Timer Mode Select bit
1 = Timerx and Timery form a single 32-bit timer
0 = Timerx and Timery act as two 16-bit timers
bit 2
Unimplemented: Read as ‘0’
bit 1
TCS: Timerx Clock Source Select bit
1 = External clock from TxCK pin (on the rising edge) 
0 = Internal clock (F
P
)
bit 0
Unimplemented: Read as ‘0’
Note 1: The TxCK pin is not available on all timers. Refer to the 
 section for the available pins.
