MC68HC(8)05PV8/A — Rev. 1.9
FOLV1 – Force Output Level 1
OLVL1 – Output Level 1
CLK12 – Output Compare 1 clocks output latch 2
FOLV2 – Force Output Level 2
OLVL2 – Output Level 2
The FOLV1 bit always reads as zero. Writing a zero at this position
has no effect. Writing a one at this position will force the OLVL1 bit to
the corresponding output level latch, thus appearing at pin TCMP1.
Note that the force output compare 1 does not affect the OCF1 bit of
the status register.
Value of output level is clocked into output level register by the next
successful output compare 1 and will appear on the TCMP1 pins.
If this bit is set to 1, a successful compare of compare register 1 loads
the OLVL1 bit to the output latch 2. This feature can be used to get
output pulses as short a E/4 while using only one interrupt.
The FOLV2 bit always reads as zero. Writing a zero at this position
has no effect. Writing a one at this position will force the OLVL2 bit to
the corresponding output level latch thus appearing at pin TCMP2.
Note that the force output compare 2 does not affect the OCF2 bit of
the status register.
Value of output level is clocked into output level register by the next
successful output compare 2, and will appear on the TCMP2 pin.
