Enable/Disable
The key-input interrupts can be enabled and disabled in pairs using the Key-input mode register (03F9
input interrupt register (0041
enable flag (I flag). The input signal edge that triggers the Key-input interrupt can be selected by setting the P10 Key-
input edge select bits (bits 0 and 1 at 03F9
interrupt pins to input.
