71M6541D/F/G and 71M6542F/G Data Sheet
Rst Wk Dir Description
Enables the remote digital isolation interface, which transforms the IBP-IBN
0 0 R/W pins into a digital balanced differential pair. Thus, enabling these pins to
interface to the 71M6x01 isolated sensor.
0 0 R Response from remote read request.

R/W
Indicates that a count error has occurred in the RTC and that the time is not
trustworthy. This bit can be cleared by writing a 0.
RTC adjust. See 2.5.4 Real-Time Clock (RTC).
R/W 0x0FFBF ≤ RTC_P ≤ 0x10040
Note: RTC_P[16:0] and RTC_Q[1:0] form a single 19-bit RTC adjustment value.
R/W
RTC adjust. See 2.5.4 Real-Time Clock (RTC).
Note: RTC_P[16:0] and RTC_Q[1:0] form a single 19-bit RTC adjustment value.
Freezes the RTC shadow register so it is suitable for MPU reads. When
R/W RTC_RD is read, it returns the status of the shadow register: 0 = up to date, 1
= frozen.
R Time remaining until the next 1 second boundary. LSB = 1/256 second.
R/W The target minutes register. See RTC_THR below.
R/W
The target hours register. The RTC_T interrupt occurs when RTC_MIN
becomes equal to RTC_TMIN and RTC_HR becomes equal to RTC_THR.
Freezes the RTC shadow register so it is suitable for MPU writes. When
RTC_WR is cleared, the contents of the shadow register are written to the
R/W RTC counter on the next RTC clock (~500 Hz). When RTC_WR is read, it
returns 1 as long as RTC_WR is set. It continues to return one until the RTC
counter actually updates.
The RTC interface registers. These are the year, month, day, hour, minute
and second parameters for the RTC. The RTC is set by writing to these
registers. Year 00 and all others divisible by 4 are defined as a leap year.
SEC 00 to 59
MIN 00 to 59

HR 00 to 23 (00 = Midnight)
DAY 01 to 07 (01 = Sunday)
DATE 01 to 31
MO 01 to 12
YR 00 to 99
Each write operation to one of these registers must be preceded by a write to
0x20A0.
R/W Analog RTC frequency adjust register.
