R#	Attribute	Content	Explanation	Default	Latched
6	R/W	RTC 6	Real-time clock	OFF	NO
7	R/W	RTC 7	Real-time clock	OFF	NO
8	R/W	RTC 8	Real-time clock	OFF	NO
9	R/W	RTC 9	Real-time clock	OFF	NO
10	R/W	RTC 10	Real-time clock	OFF	NO
11	R/W	RTC 11	Real-time clock	OFF	NO
12	R/W	RTC 12	Real-time clock	OFF	NO
13	R/W	RTC 13	Real-time clock	OFF	NO
14	R/W	RTC 14	Real-time clock	OFF	NO
15	R/W	RTC 15	Real-time clock	OFF	NO

Symbol “R” refers to ready only; “R/W” refers to read and write.

R#0: RTC 0

Explanations:

When the RTC function is enabled, and the assigned trigger condition is true, RTU-EN01 will set the bit device R0 to ON and continue to output or stop according to the set time.

R#1 ~ #15: RTC 1 ~ 15

Explanations:

Please refer to R#0.
