5.4 Time 

There is one set of Time registers supported by the PMC-T402 – Year / Month / Day / Hour / Minute / 

Second (Register # 60000 to 60002). All registers within a Time register set must be written in a single 

transaction. Writing to the Millisecond register (60003) is optional during a Time Set operation. When 

broadcasting time, the function code must be set to 0x10 (Pre-set Multiple Registers). Incorrect date 

or time values will be rejected by the device. In addition, attempting to write a Time value less than 

Jan 1, 2000 00:00:00 will be rejected.
