CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Input Ports)
The contents that can be selected with the input port mask
option are as follows:
(1) An internal pull-down resistance can be selected for each
of the four bits of the input ports (K00–K03). Having
selected "pull-down resistance disabled", take care that
the input does not float. Select "pull-down resistance
enabled" for input ports that are not being used.
(2) The input interrupt circuit contains a noise rejection
circuit to prevent interrupts form occurring through
noise. The mask option enables selection of the noise
rejection circuit for each separate pin series. When "use"
is selected, a maximum delay of 0.5 ms (fosc = 32 kHz)
occurs from the time an interrupt condition is established
until the interrupt factor flag (IK) is set to "1".
Table 4.3.1 list the input port control bits and their ad-
dresses.
