16. Simplified RTC
General Description
16.1
ML62Q1000 series has the simplified RTC (RTC: Real Time Clock).
The simplified RTC counts up from 00 minutes 00 seconds to 59 minutes 59 seconds in the unit of one second and also
generates an interrupt request periodically.
For the interrupt enable/request flags, etc. described in this chapter, refer to Chapter 5 "Interrupts".
Table 16-1 shows the availability of the Simplified RTC.

16.1.1 Features
•
A desired periodical interrupt request can be chosen from among four types (0.5, 1, 30 and 60 seconds).
•
Counting operation is continued all the time, except when operating in the STOP/STOP-D mode.
•
A function to prevent erroneous writing to the simplified RTC minute/second counter included.
•
The simplified RTC minute/second counter continues counting operation even when a reset (other than power-on
reset) is generated.
