8.4.1 Timer Output Compare Registers
MC68HC711D3 — Rev. 2
MOTOROLA
All output compare registers are 16-bit read-write. Each is initialized to $FFFF at
reset. If an output compare register is not used for an output compare function, it
can be used as a storage location. A write to the high-order byte of an output
compare register pair inhibits the output compare function for one bus cycle. This
inhibition prevents inappropriate subsequent comparisons. Coherency requires a
complete 16-bit read or write. However, if coherency is not needed, byte accesses
can be used.
For output compare functions, write a comparison value to output compare
registers TOC1–TOC4 and TI4/O5. When TCNT value matches the comparison
value, specified pin actions occur.
