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 31-16 Unimplemented: Read as ‘0’
bit 15 ON: Timer On bit
(1)
1 = Timer is enabled
0 = Timer is disabled
bit 14 Unimplemented: Read as ‘0’
bit 13 SIDL: Stop in Idle Mode bit
1 = Discontinue operation when device enters Idle mode
0 = Continue operation even in Idle mode
bit 12 TWDIS: Asynchronous Timer Write Disable bit
1 = Writes to TMR1 are ignored until pending write operation completes
0 = Back-to-back writes are enabled (Legacy Asynchronous Timer functionality)
bit 11 TWIP: Asynchronous Timer Write in Progress bit
In Asynchronous Timer mode:
1 = Asynchronous write to TMR1 register in progress
0 = Asynchronous write to TMR1 register complete
In Synchronous Timer mode:
This bit is read as ‘0’.
bit 10-8 Unimplemented: Read as ‘0’
bit 7 TGATE: Timer 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
bit 6 Unimplemented: Read as ‘0’
bit 5-4 TCKPS<1:0>: Timer Input Clock Prescale Select bits
11 = 1:256 prescale value
10 = 1:64 prescale value
01 = 1:8 prescale value
00 = 1:1 prescale value
Note 1: When using 1:1 PBCmLK divisor, the user’s software should not read/write the peripheral SFRs in the
SYSCLK cycle immediately following the instruction that clears the module’s ON bit.
