When RTCD increments to reach 00000h, The 20-bit word stored into RTCPH, RTCPL registers is loaded
in RTCD.
Figure 53 : DIVIDER Counters
Bit 15 to bit 4 of RTCPH and RTCDH are not used. When reading, the return value of those bit will be
zeros.
16.1.4 - RTCH & RTCL: RTC Programmable COUNTER Registers
The RTC has 2 x 16-bit programmable counters which count rate is based on the basic time reference (for
example 1 second). As the clock oscillator may be kept working, even in power down mode, the RTC
counters may be used as a system clock. In addition RTC counters and registers are not modified at any
system reset. The only way to force their value is to write them via the XBUS.
Those counters are write protected as well. The bit RTOFF of the RTCCON register must be set (RTC
dividers and counters are stopped) to enable a write operation on RTCH or RTCL.
A write operation on RTCH or RTCL register loads directly the corresponding counter. When reading, the
current value in the counter (system date) is returned.
The counters keeps on running while the clock oscillator is working.
RTCL (EC0Eh)
RTCH (EC10h)
Note: Those registers are nor reset
