Use TF_PR[3:0] to set the nominal value for tDISC
according to the following formula:
tDISC nominal = 238ms + 16ms x N
where N is the decimal value of the binary words
TF_PR[3:0].
A reset sets R27h = 47h, which sets tDISC nominal =
350ms as shown in the Electrical Characteristics. Use
R27h in conjunction with the two TDISC[1:0] bits in reg-
ister R16h to program the values of tDISC from 60ms to
almost 340ms with a 16ms resolution.
Example: Set TD_PR[3:0] = 1111b, TDISC[1:0] = 11b
Then:
tDISC = 2 x tDISC nominal
= 2 x (238ms + 16ms x 15)
= 956ms
Note: The programmed value has the same percent-
age tolerance as the value specified in the Electrical
Characteristics.
