I 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.
P Power Ground Input. The TGND2 should connect with GND pin.
P Power Ground Input. The TGND1 should connect with GND pin.
4-bit bi-directional I/O port 10. The output type of I/O pad can also be selected by
mask option MO_10PP[3..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 pad as input pad, “1” must be outputted before reading.
PRT10[0] is shared with DTMFO of DTMF generator. PRT10[1] is multiplexed with
KEYTONE output.
8-bit bi-directional 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 as external interrupt
sources.
O Dedicated Ground for PWM output.
O The PWM output can drive speaker or buzzer directly. Set the bit2 of VOC register as
one to turn on PWM. Using VDD & PWM to drive output device.
8-bit bi-directional I/O port C. The output type of I/O pad can also be selected by
mask option MO_CPP[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.
PRTC[7:4] is shared with Key Scan Dedicated Input SCNI[3:0]. The Key Scan
function can be disabled by clearing MO_LCDKEY mask option to ‘0’.
P Dedicated power input for RAM
COM[32..63] pads are shared with SEG[95..64] outputs. The functions of the pads to
be COM drivers or SEG drivers can be selected by mask option MO_COM[1..0].
Please refer to LCD driver configuration for details.
SEG[63..44] 141~160 O LCD segment SEG[63..44] outputs.
LCD segments share pads with key scan out SCNO[19..0]. The key scan function of
these pins can be disabled by mask option clearing MO_LCDKEY to ‘0’, then
SGKY[43..24] function as LCD segment driver only. Setting MO_LCDKEY to ‘1’
will turn on the key scan function.
