Functional Description
Keyboard matrix
C1~C8 and R1~R5 form a keyboard matrix. To-
gether with a standard 5 8 keyboard, the key-
board matrix is used for dialing entries. In
addition,thekeyboardmatrixalsoprovidesresis-
tor options for different dialing specification se-
lections. The keyboard arrangement for the
HT9320 series are shown in the
