corresponding data type and format sent back by the 71M6xx3 remote sensor and how the data is stored
in RMT_RD[15:8] and RMT_RD[7:0]. The MPU selects which of the three phases is read by asserting the
proper code in the RCMD[1:0] field, as shown in
.
With hardware and trim-related information on each connected 71M6xx3 Isolated Sensor available to the
71M6543, the MPU can implement temperature compensation of the energy measurement based on the
individual temperature characteristics of the 71M6xx3 Isolated Sensors. See

TRIMT[7:0] is the VREF trim value for all 71M6xx3 devices. Note that the TRIMT[7:0] 8-bit value is formed
by RMT_RD[8] and RMT_RD[7:1]. See the 71M6xxx Data Sheet for the equations related to

TRIMBGB[7:0] and TRIMBGD[7:0] are trim values used for characterizing the 71M6113 (0.5%) and 71M6203
