12.5.4.The configuration possibilities of the Key-Thresholds and the Key-Interrupt

-

Port NO_SPB_P_B[7:0]=FFh

-

Port UDB_P_B[7:0]=00h

-

External pull down, KEY0 is high active

-

Key interrupt will be generated on a 1ms…2ms

debounced L-H transient of I_P_B[7:0]

-

UDB_P_B[7:0] has no influence on the comperator

digital input threshold level
