CMOS IN/OUT
These pins form a 4´5 keyboard matrix which can perform keyboard input detection and dialing specification setting functions. When on-hook (HKS=high) all the pins are set high. While off-hook the column group (C1~C5) remains low and the row group (R1~R4) is set high for key input detection. An inexpensive single contact 4´5 keyboard can be used as an input device. Pressing a key connects a single column to a single row, and actuates the system oscillator that results in a dialing signal output. If more than two keys are pressed at the same time, no response occurs. The key-in debounce time is 20ms. Refer to the keyboard information for keyboard arrangement and to the functional description for dialing specification selection.

This pin is used to monitor the status of the hook-switch and its combination with
HFI/HDI can control the PO pin output to make or break the line.
