Description
Data Bit Select
I
BIT4 = 0Î The parallel mode is use 8-bit data bus.
BIT4 = 1Î The parallel mode is use 4-bit data bus (Default).
This pin must be kept high for serial mode.
Parallel/Serial Select
I
P/ S = 0 Î The MPU interface is serial mode (Default). See the setting of
DB[7:6].
P/ S = 1 Î The MPU interface is parallel mode.

The relationship of the power is VOUT>V0≧V1≧V2≧V3≧V4≧VSS
Capacitor Input
I _{These are used to connect capacitors for internal Booster.}
O Booster Output
Reference Voltage Input
I
This is the external reference voltage input when the internal one is
disabled.

Voltage Adjustment
I
Applies voltage between V0 and VSS by connecting a resistor divider.
Clock Select
I
This pin is used to select the clock source. When CLK_SEL is “1”, the
clock is generated by internal RC oscillator. When CLK_SEL is “0”, the
system clock is driven by external pin - EXT_CLK.
External Clock
I When CLK_SEL is “0”, this pin is the external clock input. When CLK_SEL
is “1”, this pin is not used and has to be connected to VDD or GND.
