4.3.8 Port input threshold control register (PITHL1, PITHL3 to PITHL7, PITHL10, PITHL12, PITHL15)
These registers are used to specify the threshold value of the input buffers for P10, P11, P13, P14, P16, P17, P30,
P43, P50, P52 to P54, P60 to P63, P70, P71, P73, P75 to P77, P107, P125, P150, P152, and P153 in 1-bit units.
These registers can set V
IL to 0.5 EVDD for the serial communications interface and some external interrupts.
The PITHL1, PITHL3 to PITHL7, PITHL10, PITHL12, and PITHL15 registers can be set by a 1-bit or 8-bit memory
manipulation instruction.
Reset signal generation clears these registers to 00H.
