NLPTH0
This register allows the user to program the level of the Non-Linear
Processor Threshold. The 16 bit 2’s complement linear value
defaults
to
1AAh. The maximum value is 7FFFh = 0.9999. Higher value corresponds
to higher threshold. The high byte is in Register 2 and the low byte is in
Register 1.
