5. CODE DEVELOPMENT & DEMO SYSTEM:
User can use “EzSpeech“ software tool to develop the desired functions. For details, please see EzSpeech
user manual. After finishing the code programming, user will get 2 files of “.bin” and “.htm”, the binary file
and function check list. User can download the “.bin” file into 4EA_DB demo board to demonstrate the
AVxx16K function. The related mapping of 4EA_DB is as below,

Description
PRA0 performs OKY input.
PRA1/PRA2 perform IO1/IO2 input mode.
PRB0/PRB1 perform IO1/IO2 output mode.
PWM output to directly drive speaker.
OSC1 connect 150K ohms resistor to Vdd.
For some input type option, user may need to connect an external resistor. Please refer to the table below,

Description
The same.
Almost the same.
Need to connect 1M external resistor to GND.
Need to connect 10M external resistor to GND.
The same.
Once the function has been approved, user only need to send the “.bin” file to Aplus for co de tape-out.
