Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown

TON: Timer1 On bit⁽¹⁾
1 = Starts 16-bit Timer1
0 = Stops 16-bit Timer1
Unimplemented: Read as ‘0’
TSIDL: Timer1 Stop in Idle Mode bit
1 = Discontinues module operation when device enters Idle mode
0 = Continues module operation in Idle mode
Unimplemented: Read as ‘0’
TGATE: Timer1 Gated Time Accumulation Enable bit
When TCS = 1:
This bit is ignored.
When TCS = 0:
1 = Gated time accumulation is enabled
0 = Gated time accumulation is disabled
TCKPS<1:0> Timer1 Input Clock Prescale Select bits
11 = 1:256
10 = 1:64
01 = 1:8
00 = 1:1
Unimplemented: Read as ‘0’
TSYNC: Timer1 External Clock Input Synchronization Select bit⁽¹⁾
When TCS = 1:
1 = Synchronizes external clock input
0 = Does not synchronize external clock input
When TCS = 0:
This bit is ignored.
TCS: Timer1 Clock Source Select bit⁽¹⁾
1 = External clock from T1CK pin (on the rising edge)
0 = Internal clock (FP)
Unimplemented: Read as ‘0’
Note 1: When Timer1 is enabled in External Synchronous Counter mode (TCS = 1, TSYNC = 1, TON = 1), any
attempts by user software to write to the TMR1 register are ignored.
