Pin Function
Note: * This pin can always be used as the KINm input pin. (n = 1 or 0, m = 9 or 8)
7.11.5
Port A has an on-chip input pull-up MOS function that can be controlled by software. This input
pull-up MOS function can be specified as on or off on a bit-by-bit basis.
The input pull-up MOS for pins PA7 to PA4 is always off when IICS is set to 1. When the
keyboard buffer control pin function is selected for pins PA7 to PA2, the input pull-up MOS is
always off.
Table 7.6 summarizes the input pull-up MOS states.
