I/O
P Dedicated Power for Pulse Width Modulation output.
O Pulse Width Modulation output.
O Complementary output to PWMP.
P Dedicated Power for Pulse Width Modulation output.
8-bit bi-directional I/O port 17 is shared with LCD segment pads SEG[39..32].
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.
8-bit bi-directional I/O port 15 is shared with LCD segment pads SEG[31..24].
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 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).
