Real-time clock (RTC)
207/346
RTC divider counter registers (RTCDH and RTCDL)
The divider counter registers (the basic reference clocks) include the RTC divider high
(RTCDH) and RTC divider low (RTCDL). These registers are read-only. They are reloaded
with the value stored in the prescaler registers, RTCPH and RTCPL. To get accurate time
measurements, the value of the divider can be read by reading the RTCDH and RTCDL.
When a bit is changed in the prescaler register, the value is loaded into the divider. When
the divider increments to reach 00000h, the 20-bit word stored in RTCPH or RTCPL is
loaded into it.
Note:
Bits 15 to 4 of the RTCDH are not used. When reading this register, the return value of these
bit is zero.
Note:
Neither the RTCDH nor the RTCDL counter registers can be reset.
