Boot-Up Delay

Once EN is above its threshold and the software enable

bit is set, a boot-up delay occurs before monitoring

begins. This delay is configured in register 77h as shown

in Table 4, and it is stored as an 8-bit value calculated

as follows:

BOOT

= (5 x 10

-6

) x 2

x (16 + b) + 480µs

where t

BOOT

is in seconds, a is the decimal value of the

4 MSBs and b is the decimal value of the 4 LSBs.
