Unused inputs should not be left floating. Tie either HIGH or LOW as appropriate. Outputs should only be pulled up or down to ensure signals at power-up
and in standby. Note also that no pins should be driven while the device is powered down.

Analog VCC. Connect this pin to 3.3V power source. This signal provides
power to the analog section of the chip.

USB D– Signal. Connect to the USB D– signal.
USB D+ Signal. Connect to the USB D+ signal.
8051 Address Bus. This bus is driven at all times. When the 8051 is
addressing internal RAM it reflects the internal address.
8051 Data Bus. This bidirectional bus is high-impedance when inactive,
input for bus reads, and output for bus writes. The data bus is used for
external 8051 program and data memory. The data bus is active only for
external bus accesses, and is driven LOW in suspend.
Program Store Enable. This active-LOW signal indicates an 8051 code
fetch from external memory. It is active for program memory fetches from
0x4000–0xFFFF when the EA pin is LOW, or from 0x0000–0xFFFF when
the EA pin is HIGH.
Breakpoint. This pin goes active (HIGH) when the 8051 address bus
matches the BPADDRH/L registers and breakpoints are enabled in the
BREAKPT register (BPEN = 1). If the BPPULSE bit in the BREAKPT
register is HIGH, this signal pulses HIGH for eight 12-/24-/48-MHz clocks.
If the BPPULSE bit is LOW, the signal remains HIGH until the 8051 clears
the BREAK bit (by writing 1 to it) in the BREAKPT register.
