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].
26 ~ 33
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[15..8]. The
function of the pad can be selected individually by mask options MO_LIO15[7..0].
34 ~ 41
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].
42 ~ 49
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.

Voltage Regulator Output. VDD is regulated to generate LVREG, which is in turns
pumped to LVP. Adjust resistor between LGS1 and LVREG to set LVREG voltage.
96 I Regulator Voltage Setting
97 O Reference Voltage Output. Fixed 0.9 Volt DC reference voltage
98 P Power ground Input.
99
O
DAC Voice Output. Set the bit 1 and clear the bit 0 of VOC (DA = ‘1’ and OP = ‘0’)
register to turn on DAC with VO output.
100
O
Alternate output of DAC. Set both bit 1 and bit 0 of VOC register (DA = ‘1’ and OP =
‘1’) to turn on DAC with DAO output as well as OP comparator.
101
I
Inverting input of OP Amp. Set the bit 0 of VOC register (OP = ‘1’) to turn on OP
comparator.
102 I Non-inverting input of OP Amp.
103 O Output of OP Amp.
104
I
System Reset input pin. Level trigger, active low on this pin will put the chip in reset
state.
