Step
Release the Explorer 16 Development Board’s
S3 push button.
Configure oscilloscope as follows:
• Time-base = 100 µs/Division
Depress the Explorer 16 Development Board’s
S6 push button.
Depress the Explorer 16 Development Board’s
S4 push button.
Use the S4 and S6 push buttons to configure
the Volatile Wiper 1 register to either near V
or near V
Configure Scope to Capture on Channel 2.
Depress the Explorer 16 Development Board’s
S5 push button.
Unplug Power from the Explorer 16
Development Board.
Depress the Explorer 16 Development Board’s
S3 push button.
Power up the programmed Explorer 16
Development Board and depress and release
the MCLR push button.
Release the Explorer 16 Development Board’s
S3 push button.
Unplug Power from the Explorer 16
Development Board and remove the
MCP46XXDM-PTPLS board.

While S6 is depressed, the voltage
on Wiper 1 (VW1) increases.
While S4 is depressed, the voltage
on Wiper 1 (VW1) decreases.

While S5 is depressed, the volatile
Wiper 1 register is read, this value is
written to the Non-Volatile Wiper 1
register, and then approximately a
10 ms delay occurs while the NV
write cycle occurs. Capture will look
