RTCSS.6
Real Time Clock Subseconds. This register represents the subsecond value of
the RTC. It can be read only when the RTCRE bit is set, and writes are not
permitted. It is reset to 00h when the RTCWE bit is cleared. The register counts
from 0h to FFh.
Reserved. These bits will be 0 when read.
Real Time Clock Seconds. This register represents the second value of the
RTC. This register can be read only when the RTCRE bit is set, and can only be
modified when the RTWE bit is set. Consult the description of the RTCWE bit
for the programming protocol for this register. This register counts from 0h to
3Bh (0 to 59 seconds), and any writes to this register out-side of that range will
generate an inaccurate count.
Reserved. These bits will be 0 when read.
Real Time Clock Minutes. This register represents the minute value of the
RTC. This register can be read only when the RTCRE bit is set, and can only be
modified when the RTCWE bit is set. Consult the description of the RTCWE bit
for the programming protocol for this register. This register counts from 0h to
3Bh (0 to 59 minutes), and any writes to this register out-side of that range will
generate an inaccurate count.
