Description

refer to LCD driver configuration for details.

SEG[47..40]/D[7..0]

155~

162

LCD segment SEG[47..40] outputs share pads with data bus D[7..0] of external

memory.

SEG[39..16]/A[23..0]

163~

186

LCD segment SEG[39..16] outputs share pads with address bus A[23..0] of external

memory.

OE/SEG15

187

Output Enable control of external memory shares pad with SEG[15]. The function of

the pin is selected by mask option MO_EXMEM.

When used as Output Enable control pin, this pin control the tri-state buffer of external

memory data bus.

WE/SEG14

188

Write Enable control of external memory shares pad with SEG[14]. The function of the

pin is selected by mask option MO_ EXMEM.

When used as Write Enable control pin, this pin controls Write Enable input of the

external memory device.

CS0/SEG13

Chip Select 0 of external memory shares pad with SEG[13]. The function of the pin is

selected by mask option MO_ EXMEM.

When used as Chip Enable control pin, this pin select or de-select the external memory

device based on the address been accessed.

CS1/SEG12

Chip Select 1 of external memory shares pad with SEG[12]. The function of the pin is

selected by mask option MO_ EXMEM.

When used as Chip Enable control pin, this pin select or de-select the external memory

device based on the address been accessed.

CS2/SEG11

Chip Select 2 of external memory shares pad with SEG[11]. The function of the pin is

selected by mask option MO_ EXMEM.

When used as Chip Enable control pin, this pin select or de-select the external memory

device based on the address been accessed.

CS3/SEG10

Chip Select 3 of external memory shares pad with SEG[10]. The function of the pin is

selected by mask option MO_ EXMEM.

When used as Chip Enable control pin, this pin select or de-select the external memory

device based on the address been accessed.

PRT15[1..0]/SEG[9..8]

2-bit bi-directional I/O port 15 is shared with LCD segment pads SEG[9..8]. The

function of the pad can be selected individually by mask options MO_LIO15[1..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[1..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.

PRT17[7..0]/SEG[7..0]

7~14

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.

I: Input, O: Output, B: Bidirectional, P: Power.
