The PIC32MX3XX/4XX Real-Time Clock and Calendar
(RTCC) module is intended for applications where
accurate time must be maintained for extended periods
of time with minimal or no CPU intervention. Low-
power optimization provides extended battery lifetime
while keeping track of time.
Following are some of the key features of this module:
• Time: Hours, Minutes and Seconds
• 24-Hour Format (Military Time)
• Visibility of One-Half-Second Period
• Provides Calendar: Weekday, Date, Month and
