Due to the asynchronous nature of Timer1 operating in
Asynchronous Clock mode, reading and writing to the
TMR1
between the asynchronous clock source and the inter-
nal PBCLK (Peripheral Bus Clock). Timer1 features a
Timer Write Disable (TWDIS) control bit (T1CON<12>)
and a TWIP (TImer Write in Progress) Status bit
(T1CON<11>). These bits provide the user with 2
options for safely writing to the TMR1 Count register
while Timer1 is enabled. These bits have no affect in
Synchronous Clock modes.
• Option 1 – Legacy Timer1 Write mode, TWDIS bit
• Option 2 – New synchronized Timer1 Write mode,
Writing to the TMR1 Count register requires 2 to 3
asynchronous external clock cycles for the value to be
synchronized into the TMR1 Count register.
Reading from the TMR1 Count register requires 2
PBCLK cycle delays between the current unsynchro-
nized value in the TMR1 Count register and the
synchronized value returned by the read operation. In
other words, the value read is always 2 PBCLK cycles
behind the actual value in the TMR1 Count register.
The following steps should be performed to properly
configure the Timer1 peripheral for Asynchronous
Counter mode operation.

= 0. To determine when it is safe to write to the
TMR1 Count register, it is recommended to poll
the TWIP bit. When TWIP = 0, it is safe to perform
the next write operation to the TMR1 Count regis-
ter. When TWIP = 1, the previous write operation
to the TMR1 Count register is still being synchro-
nized and any additional write operations should
wait until TWIP = 0.
TWDIS bit = 1. A write to the TMR1 Count register
can be performed at any time. However, if the pre-
vious write operation to the TMR1 Count register
is still being synchronized, any additional write
operations are ignored.
Clear control bit, ON (T1CON<15>) = 0, to
disable Timer1.
Select the desired timer prescaler using bits,
TCKPS<1:0> (T1CON<5:4).
Set control bit, TCS (T1CON<1>) = 1, to select
an external clock source.
Set control bit, TSYNC (T1CON<2>) = 0, to
disable synchronization.
Clear Timer Register, TMR1.
Load Period Register, PR1, with desired 16-bit
match value.
If timer interrupts are used, refer to 13.5 “Timer
Interrupts” for interrupt configuration steps.
Set control bit, ON (T1CON<15>) = 1, to enable
Timer1.
