Alternatively used for LCD segment output.

O 1-bit or 4-bit output port.

Alternatively used for LCD segment output.

O Common signal output for LCD display

I LCD power control

I LCD power supply.

Voltage dividing resistors are assignable by

software

– Main power supply

– Main Ground

I System reset pin

– Crystal, or ceramic oscillator pin for main system

clock. (For external clock input, use XIN and input

XIN’s reverse phase to XOUT)

– Crystal oscillator pin for subsystem clock. (For

external clock input, use XTIN and input XTIN’s

reverse phase to XTOUT)

I Test signal input (must be connected to VSS for

normal operation)

I Input pin for checking device power.

Normal operation is high level and PLL/IFC

operation is stopped at low level.

I External VCOFM/AM signal inputs.

O PLL’s phase error output

I FM/AM intermediate frequency signal inputs.

– PLL/IFC power supply

– PLL/IFC ground
