The Real-Time Clock and Calendar (RTCC) provides
on-chip, hardware-based clock and calendar function-
ality with little or no CPU overhead. It is intended for
applications where accurate time must be maintained
for extended periods with minimal CPU activity and
with limited power resources, such as battery-powered
applications.

Key features include:
• Time data in hours, minutes and seconds, with a
• 24-hour format (Military Time) display option
• Calendar data as date, month and year
• Automatic, hardware-based day of the week and
• Time and calendar data in BCD format for
• Highly configurable alarm function
• External output pin with selectable alarm signal or
• User calibration feature with auto-adjust
A simplified block diagram of the module is shown in
Figure 20-1. The SOSC and RTCC will both remain
running while the device is held in Reset with MCLR
and will continue running after MCLR is released.
