The factory programmed ID ROM can be programmed to customers specification. Contact Texas Instruments
for details.
discharge count registers (DCRH/CRL0
The DCRH high-byte register (address 010F hex) and the DCRL low-byte register (address 010E hex), which
contain the count of the discharge, are incremented whenever V_SRP < V_SRN (1 LSB = 3.05 µV-hr). These
registers continue to count beyond FFFF hex, so proper register maintenance should be done by the host
system. The TMP/CLR register forces the reset of both the DCRH and DCRL to zero when the DCR bit is set.
charge count registers (CCRH/CCRL)
The CCRH high-byte register (address 010D hex) and the CCRL low-byte register (address 010C hex), which
contain the count of the charge, are incremented whenever V_SRP > V_SRN (1 LSB = 3.05 µV-hr). These registers
continue to count beyond FFFF hex, so proper register maintenance should be done by the host system. The
TMP/CLR register forces the reset of both the CCRH and CCRL to zero when the CCR bit is set.
