Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

â1â = Bit is set

U = Unimplemented bit, read as â0â

â0â = Bit is cleared

x = Bit is unknown

bit 31-16 Unimplemented: Read as â0â

bit 15

ON: Timer On bit(1)

1 = Timer is enabled

0 = Timer is disabled

bit 14 Unimplemented: Read as â0â

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 â0â.

bit 10-8 Unimplemented: Read as â0â

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 â0â

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 userâs software should not read/write the peripheral SFRs in the

SYSCLK cycle immediately following the instruction that clears the moduleâs ON bit.
