11.3.4
OCRAR and OCRAF are 16-bit readable/writable registers. When the OCRAMS bit in TOCR is
set to 1, the operation of OCRA is changed to include the use of OCRAR and OCRAF. The
contents of OCRAR and OCRAF are automatically added alternately to OCRA, and the result is
written to OCRA. The write operation is performed on the occurrence of compare-match A. In the
1st compare-match A after setting the OCRAMS bit to 1, OCRAF is added. The operation due to
compare-match A varies according to whether the compare-match follows addition of OCRAR or
OCRAF. The value of the OLVLA bit in TOCR is ignored, and 1 is output on a compare-match A
following addition of OCRAF, while 0 is output on a compare-match A following addition of
OCRAR.
When using the OCRA automatic addition function, do not select internal clock φ/2 as the FRC
input clock together with a set value of H'0001 or less for OCRAR (or OCRAF).
OCRAR and OCRAF should always be accessed in 16-bit units; cannot be accessed in 8-bit units.
OCRAR and OCRAF are initialized to H'FFFF.
11.3.5
OCRDM is a 16-bit readable/writable register in which the upper eight bits are fixed at H'00.
When the ICRDMS bit in TOCR is set to 1 and the contents of OCRDM are other than H'0000,
the operation of ICRD is changed to include the use of OCRDM. The point at which input capture
D occurs is taken as the start of a mask interval. Next, twice the contents of OCRDM is added to
the contents of ICRD, and the result is compared with the FRC value. The point at which the
values match is taken as the end of the mask interval. New input capture D events are disabled
during the mask interval. A mask interval is not generated when the contents of OCRDM are
H'0000 while the ICRDMS bit is set to 1.
OCRDM should always be accessed in 16-bit units; cannot be accessed in 8-bit units. OCRDM is
initialized to H'0000.
