BAUD1:BAUD0 Hardware control of the MCP215X baud rate.
BAUD0 is connected to Header RA0 signal and BAUD1 is
connected to Header RA0 signal
S S = 9600 Baud
S O = 19200 Baud
O S = 57600 Baud
O O = 115200 Baud
MODE1:MODE0 Hardware program mode selection. Operation
is dependant on the Host Controller program.
00077 - HPC.asm Operation
S S = Direct-to-PC
S O = Reserved
O S = Data Echo
O O = Data Logger (250 Byte data transfer)
EN Hardware control of the MCP215X EN signal.
EN is connected to Header RA0 signal.
S = Signal Connected to V SS
O = Signal Connected to V DD
Connects the U1 pin 1 to either the BAUD0 signal ( MCP215X )
or to the RXPDREF signal ( MCP2140 ).
Connects the U1 pin 18 to either the BAUD1 signal ( MCP215X )
or to the RXPD signal ( MCP2140 ).
Connects the U1 pin 3 to either the RXIR signal ( MCP215X ) or
to the PHACT signal ( MCP2140 ).
Connects the “IR Link” signal to either the U1-17 signal (CD) for
the MCP2150 device or to the U1-10 signal (DSR) for the
MCP2155 or MCP2140 device.
S = Signal Connected to V SS
O = Signal Connected to V DD
The MCP2140 has a fixed baud rate
of 9600 baud.
S = Signal Connected to V SS
O = Signal Connected to V DD
These operational modes are for the
00077 - HPC.asm program with the
PICDEM? HPC Explorer Board.
The MCP2140 does not use this
signal.
