MCP215X/40 Developer’s Daughter Board User’s Guide
Figure 2-3 shows the component layout for the MCP215X/40 Developer ’s Daughter
Board and the operation of the JP1, JP2, JP3, JP4 and JP5 jumpers. When the jumper
is open, the signal is pulled high. When the jumper is shorted, the signal is pulled to
ground.
Jumpers JP1 and JP2 are used to specify the MCP215X’s baud rate. The MCP2140
has a fixed baud rate of 9600 baud. The BAUD0 signal is connected to Header H1/H3’s
RB4 pin. The BAUD1 signal is connected to Header H1/H3’s RB5 pin.
Jumpers JP1 and JP2 are used to specify the Host Controller program mode.
The MODE0 signal is connected to Header H1/H3’s RB0 and RA1 pins. The MODE1
signal is connected to Header H1/H3’s RC2 and RE3 pins.
Note:
When using header H3 with the PICDEM FS USB board, refer to Appendix
E. “Using the MCP215X/40 Developer ’s Daughter Board with the
PICDEM? FS USB Demo Board” if the MCP215X/40 Developer ’s
Daughter Board PCB is Rev 2.
Jumper JP5 are used to specify the MCP215X’s operational state (Enable/Disable).
The MCP2140 has an automatic lower power mode, so is not controlled by a hardware
pin. The EN signal is connected to Header H1/H3’s RB3 pin.
