PIC24FJ128GA FAMILY
18.1
The RTCC module registers are organized into three
categories:
• RTCC Control Registers
• RTCC Value Registers
• Alarm Value Registers
18.1.1
To limit the register interface, the RTCC Timer and
Alarm Time registers are accessed through corre-
sponding register pointers. The RTCC Value register
window (RTCVALH and RTCVALL) uses the RTCPTR
bits (RCFGCAL<9:8>) to select the desired timer
register pair (see Table 18-1).
By writing the RTCVALH byte, the RTCC pointer value
RTCPTR<1:0> decrements by one until it reaches ‘00’.
Once it reaches ‘00’, the MINUTES and SECONDS
value will be accessible through RTCVALH and
RTCVALL until the pointer value is manually changed.

Advance Information
The Alarm Value register window (ALRMVALH and

(ALCFGRPT<9:8>) to select the desired alarm register
pair (see Table 18-2).
By writing the ALRMVALH byte, the alarm pointer value
ALRMPTR<1:0> decrements by one until it reaches
‘00’. Once it reaches ‘00’, the ALRMMIN and
ALRMSEC
ALRMVALH and ALRMVALL until the pointer value is
manually changed.
TABLE 18-2:
Considering that the 16-bit core does not distinguish
between 8-bit and 16-bit read operations, the user must
be aware that when reading either the ALRMVALH or
ALRMVALL bytes will decrement the ALRMPTR<1:0>
value. The same applies to the RTCVALH or RTCVALL
bytes with the RTCPTR<1:0> being decremented.
