manufacturer:linear description:these pins along with the hks form a 4´4 keyboard matrix which can perform key- board input detection. when on-hook (hks=high) all the pins are set high. while off-hook the column group (c1~c3) is set low and the row group (r1~r4) remains high for input detection. pressing a key connects a single row to a single column hks and actuates the sys- tem 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. |
