PROGRAMMABLE TIMER
MC68HC705JB2
9-8
REV 1.1
1.
Disable interrupts by setting the I bit in the condition code register.
2.
Write to the OCRH. Compares are now inhibited until OCRL is written.
3.
Read the TSR to arm the OCF for clearing.
4.
Enable the output compare registers by writing to the OCRL. This also
clears the OCF ag bit in the TSR.
5.
Enable interrupts by clearing the I bit in the condition code register.
A software example of this procedure is shown below.
9.5
TIMER CONTROL REGISTER (TCR)
The timer control register is shown in Figure 9-10 performs the following
functions:
Enables input capture interrupts
Enables output compare interrupts
Enables timer overow interrupts
Control the active edge polarity of the TCAP signal on pin PB0/TCAP
Reset clears all the bits in the TCR with the exception of the IEDG bit which is
unaffected.
ICIE - INPUT CAPTURE INTERRUPT ENABLE
This read/write bit enables interrupts caused by an active signal on the PB0/
TCAP pin. Reset clears the ICIE bit.
1 =
Input capture interrupts enabled.
0 =
Input capture interrupts disabled.
