General Registers A to D (GRA to GRD)
Each general register is a 16-bit readable/writable register that can function as either an output-
compare register or an input-capture register. The function is selected by settings in TIOR0 and
TIOR1.
When a general register is used as an output-compare register, its value is constantly compared
with the TCNT value. When the two values match (a compare match), the corresponding flag
(IMFA, IMFB, IMFC, or IMFD) in TSRW is set to 1. An interrupt request is generated at this
time, when IMIEA, IMIEB, IMIEC, or IMIED in TIERW is set to 1. Compare match output can
be selected in TIOR.
When a general register is used as an input-capture register, an external input-capture signal is
detected and the current TCNT value is stored in the general register. The corresponding flag
(IMFA, IMFB, IMFC, or IMFD) in TSRW is set to 1. If the corresponding interrupt-enable bit
(IMIEA, IMIEB, IMIEC, or IMIED) in TIERW is set to 1 at this time, an interrupt request is
generated. The edge of the input-capture signal is selected in TIOR.
GRC and GRD can be used as buffer registers of GRA and GRB, respectively, by setting BUFEA
and BUFEB in TMRW.
For example, when GRA is set as an output-compare register and GRC is set as the buffer register
for GRA, the value in the buffer register GRC is sent to GRA whenever compare match A is
generated.
When GRA is set as an input-capture register and GRC is set as the buffer register for GRA, the
value in TCNT is transferred to GRA and the value in GRA is transferred to GRC whenever an
input capture is generated.
GRA to GRD must be written or read in 16-bit units; 8-bit access is not allowed. GRA to GRD are
initialized to H'FFFF by a reset.
