Reset Signal Input
This active-low input performs a hardware reset on the RA8806. It is a
Schmitt-trigger input with pull-up resistor for enhanced noise immunity;
however, care should be taken to ensure that it is not triggered if the
supply voltage is lowered.
Touch Panel Input
The left analog input pin(XL) of 4-wires touch panel.
Touch Panel Input
The right analog input pin(XR) of 4-wires touch panel.
Touch Panel Input
The top analog input pin(YU) of 4-wires touch panel.
If user want to use Touch Panel function, please add a 39K~51Kohm
external pull-up resistor on this pin.
Touch Panel Input
The bottom analog input pin(YD) of 4-wires touch panel.
PWM Output Signal
This output signal is used to control back-light module or booster circuit.
Key Pad Input
These pins are keypad inputs with pull-up resistors. For un-used input,
please keep floating.
Key Pad Output
These pins are keypad outputs. For un-used pin, please keep floating.
Clock Output
This is a multi-function output pin that depending on the value of register
REG[01h] Bit-6.
REG[01h] Bit-6 = 0: The pin is the output of internal system clock.
REG[01h] Bit-6 = 1: The pin indicate the SLEEP state of Status
Register(0: Normal Mode, 1: Sleep Mode).
LCD Driver Data Bus Select
This pin is used to select data bus of LCD driver is 8-bits or 4-bits:
0 : LCD driver data bus is 4-bits, LD[3:0] is used.
1 : LCD driver data bus is 8-bits, LD[7:0] is used.
When 4-bits data bus is used, LD[7:4] need to keep floating. RA8806T1N
does not support this function, its LCD driver data bus is fix 4-bits.
MPU Type Select
This pin is used to select MPU interface protocol:
0 : Intel 8080 series MPU interface.
1 : Motorola 6800 series MPU interface.
8080/6800 MPU Data Bus Select
This pin is used to select data bus width.
0 : 4-bits MPU I/F, DATA[3:0] is used.
1 : 8-bits MPU I/F, DATA[7:0] is used.
When 4-bits data bus is used, DATA[7:4] need to keep floating.
