Description
PRT11[7..0] 29 ~ 36
B/
O
8-bit bi-directional I/O port 11 is shared with LCD segment pads SEG[15..8]. The
function of the pad can be selected individually by mask options
MO_LIO11[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_11PP[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.
O LCD SEGMENT SEG[7..0] outputs.
O LCD COMMON Driver pads.

P Power ground Input.
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’ for RC type and ‘1’ for crystal type). For RC type oscillator, one resistor need
to be connected between FXI and GND. For crystal oscillator, one crystal need to
be placed between FXI and FXO. Please refer to application for details.
Test input pin. Please bond this pad and reserve a test point on PCB for
debugging. But for improving ESD, please connect this point with zero Ohm
resistor to GND
.
External slow clock pins. Slow clock is clock source for LCD display, TIMER1,
Time-Base and other internal blocks. Both crystal and RC oscillator are provided.
The slow clock type can be selected by mask option MO_SXTAL. Choose ‘0’ for
RC type and ‘1’ for crystal oscillator.
P Positive power Input. 0.1 μF decoupling capacitors should be placed as close to
IC VDD and GND pads as possible for best decoupling effect.
8-bit bi-directional general purpose I/O port D. The output type of I/O pad can
also be selected by mask option MO_DPP[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 the pin.
PRTD[7..2] can be used as wake-up pins. PRTD[7..6] can be used as external
interrupt sources.
