Preliminary
Off
TMR1 module uses the main
oscillator as clock source.
TMR1ON can turn on or turn off
Timer1.
TMR1 module uses the external
signal on the
RB1/T1OSO/T1CKI pin as a
clock source. TMR1ON can turn
on or turn off Timer1. DT1CK
can read the signal on the
RB1/T1OSO/T1CKI pin.
DATACCP<0> bit drives
RB1/T1OSO/T1CKI and pro-
duces the TMR1 clock source.
TMR1ON can turn on or turn off
Timer1. The DATACCP<0> bit,
DT1CK, can read and write to
the RB1/T1OSO/T1CKI pin.
RB1/T1OSO/T1CKI and
RB2/T1OSI are configured as a
2 pin crystal oscillator.
RB1/T1OSI/T1CKI is the clock
input for TMR1. TMR1ON can
turn on or turn off Timer1.
DATACCP<1> bit, DT1CK,
always reads 0 as input and can
not write to the
RB1/T1OSO/T1CK1 pin.

PORTB<2:1> function as normal
I/O
PORTB<2:1> function as normal
I/O
PORTB<2> functions as normal
I/O. PORTB<1> always reads 0
when configured as input . If
PORTB<1> is configured as out-
put, reading PORTB<1> will read
the data latch. Writing to
PORTB<1> will always store the
result in the data latch, but not to
the RB1/T1OSO/T1CKI pin. If
the TMR1CS bit is cleared
(TMR1 reverts to the timer
mode), then pin PORTB<1> will
be driven with the value in the
data latch.
PORTB<2:1> always read 0
when configured as inputs. If
PORTB<2:1> are configured as
outputs, reading PORTB<2:1>
will read the data latches. Writing
to PORTB<2:1> will always store
the result in the data latches, but
not to the RB2/T1OSI and
RB1/T1OSO/T1CKI pins. If the
TMR1CS and T1OSCEN bits are
cleared (TMR1 reverts to the
timer mode and TMR1 oscillator
is disabled), then pin
PORTB<2:1> will be driven with
the value in the data latches.
