DESCRIPTION
3’b001
Read Only 6’h00 - 6’h0C Measured cell voltage and pack voltage values. Address 001111 accesses all cell and Pack Voltage data with
and 6’h0F one read operation. See Figure 70D on page 60.
Cell values are output as 13-bit signed integers with the 14^th bit (MSB) denoting the sign, (e.g., positive full
scale is 14’h1FFF, 8191 decimal, negative full scale is 14’h2000, 8192 decimal). VBAT is a 14-bit unsigned
integer.

See 6’h10 - 6’h16 Measured temperature, Secondary reference, Scan Count. Address 011111 accesses all these data in a
individual and 6’h1F continuous read (see Figure 70D on page 60). Temperature and reference values are output as 14-bit
register
unsigned integers, (e.g., full scale is 14’h3FFF (16383 decimal)).
