Use the program registers (Table 29) to set the nominal
value for tFAULT and tSTART for all ports according to
the following formula:
tFAULT nominal = 40.96ms + 2.72ms x N
tSTART nominal = 40.96ms + 2.72ms x N
where N is the decimal value of TF_PR[3:0] or
TS_PR[3:0], respectively.
A reset sets R28h = 77h, which sets tFAULT = tSTART =
60ms as shown in the Electrical Characteristics. Use
R28h in conjunction with the two TSTART and TFAULT
bits in register R16h to program the values of tFAULT
and tSTART from about 20ms to almost 330ms with a
2.72ms resolution.
Example: Set TF_PR[3:0] = 1111b, TFAULT[1:0] = 11b
Then:
tFAULT = 4 x tFAULT nominal
= 4 x (40.96ms + 2.72ms x 15)
= 327ms
Note: The programmed value has the same percent-
age tolerance as the value specified in the Electrical
Characteristics.
