Description
will turn on the key scan function.
8-bit bi-directional I/O port 14 is shared with LCD segment pads SEG[23..16]. The
function of the pad can be selected individually by mask options MO_LIO14[7..0].
(‘1’ for LCD and ‘0’ for I/O).
The output type of I/O pad can also be selected by mask option MO_14PP[7..0] (1
for push-pull and ‘0’ for open-drain).
As the output structure of I/O pad does not contain tri-state buffer. When using the
I/O as input, “1” must be outputted before reading.
8-bit bi-directional I/O port 15 is shared with LCD segment pads SEG[16..8]. The
function of the pad can be selected individually by mask options MO_LIO15[7..0].
(‘1’ for LCD and ‘0’ for I/O).
The output type of I/O pad can also be selected by mask option MO_15PP[7..0] (1
for push-pull and ‘0’ for open-drain).
As the output structure of I/O pad does not contain tri-state buffer. When using the
I/O as input, “1” must be outputted before reading.
8-bit bi-directional I/O port 17 is shared with LCD segment pads SEG[7..0]. The
function of the pad can be selected individually by mask options MO_LIO17[7..0].
(‘1’ for LCD and ‘0’ for I/O).
The output type of I/O pad can also be selected by mask option MO_17PP[7..0] (1
for push-pull and ‘0’ for open-drain).
As the output structure of I/O pad does not contain tri-state buffer. When using the
I/O as input, “1” must be outputted before reading.
