Description
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].

B/
O
(‘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].
6 ~ 13
B/
O
(‘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].
14 ~ 21
B/
O
(‘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.

I
Inverting input of OP Amp. Set the bit 0 (OP = 1) of VOC register to turn on OP
comparator.
75 I Non-inverting input of OP Amp.
76 O Output of OP Amp.
77
I
System Reset input pin. Level trigger, active low on this pin will put the chip in reset
state.
External fast clock pin. Two types of oscillator can be selected by MO_FXTAL (‘0’
78, O, for RC type and ‘1’ for crystal type). For RC type oscillator, one resistor needs to be
79 B connected between FXI and GND. For crystal oscillator, one crystal needs to be
placed between FXI and FXO. Please refer to application circuit for details.
