GENERAL RELEASE SPECIFICATION
PROGRAMMABLE TIMER
REV 1.1
9-9
OCIE - OUTPUT COMPARE INTERRUPT ENABLE
This read/write bit enables interrupts caused by a successful compare between
the timer counter and the output compare registers. Reset clears the OCIE bit.
1 =
Output compare interrupts enabled.
0 =
Output compare interrupts disabled.
TOIE - TIMER OVERFLOW INTERRUPT ENABLE
This read/write bit enables interrupts caused by a timer overow. Reset clears
the TOIE bit.
1 =
Timer overow interrupts enabled.
0 =
Timer overow interrupts disabled.
IEDG - INPUT CAPTURE EDGE SELECT
The state of this read/write bit determines whether a positive or negative
transition on the TCAP pin triggers a transfer of the contents of the timer
register to the input capture register. Reset has no effect on the IEDG bit.
1 =
Positive edge (low to high transition) triggers input capture.
0 =
Negative edge (high to low transition) triggers input capture.
9.6
TIMER STATUS REGISTER (TSR)
The timer status register (TSR) shown in Figure 9-11 contains ags for the
following events:
An active signal on the PB0/TCAP pin, transferring the contents of the
timer registers to the input capture registers.
A match between the 16-bit counter and the output compare registers
An overow of the timer registers from $FFFF to $0000.
Writing to any of the bits in the TSR has no effect. Reset does not change the
state of any of the ag bits in the TSR.
ICF - INPUT CAPTURE FLAG
The ICF bit is automatically set when an edge of the selected polarity occurs on
the PB0/TCAP pin. Clear the ICF bit by reading the timer status register with
the ICF set, and then reading the low byte (ICRL, $0015) of the input capture
registers. Reset has no effect on ICF.
