Step 2. Write BDDS bit in Device Setup register (turn balancing
functions off during measurement)
BDDS = 1
TABLE 62. DEVICE SETUP REGISTER
R/W PAGE ADDRESS
DATA
1
010
011001
XX XXXX 1XXX XXXX
X = don’t care
Step 3. Write balance timeout setting to the Watchdog/Balance
Time register: Balance timeout code = 0000001 (20 seconds)
BTM6:0 = 000 0001
TABLE 63. BALANCE TIMEOUT REGISTER
R/W PAGE ADDRESS
DATA
1
010
010101
00 0000 1XXX XXXX
X = don’t care – the lower bits are the watchdog timeout value and
should be set to a time longer than the balance time. A value 111 1111
is suggested.
Step 4. Set up Balance Status register (from Table 59 on
page 80)
Step 4A. Write Balance Setup register: Set Auto Balance mode,
set 8 second Balance wait time, and set balance off:
BMD = 11 (Auto Balance mode)
BWT = 100 (8 seconds)
BEN = 0 (Balancing disabled)
TABLE 64. BALANCE SETUP REGISTER
R/W PAGE ADDRESS
DATA
1
010
010011
XX XX0X XXX1 0011
X = don’t care
Step 4B. Write Balance Setup register: Set Balance Status
Pointer = 1
BSP = 0001 (Balance status pointer = 1)
TABLE 65. BALANCE SETUP REGISTER
R/W PAGE ADDRESS
DATA
1
010
010011
XX XXX0 001X XXXX
X = don’t care
Step 4C. Write Balance Status register: Set bits 1, 4, 7 and 10
BAL12:1 = 0010 0100 1001
TABLE 66. BALANCE STATUS REGISTER
R/W PAGE ADDRESS
DATA
1
010
010100
XX 0010 0100 1001
Step 4D. Write Balance Setup register: Set Balance Status
Pointer = 2
