... The MCP2120/22 Developer’s Board default firmware program can be used with either the MCP2122 (default device) or the MCP2120. The MCP2122 uses the PIC’s PWM pin to generate the 16XCLK signal. If the MCP2120 is used, the program will either source a 3.6864 MHz clock or the MCP2120 will use an external crystal (not installed). ...
Page 20
... The firmware may also generate a clock source which will be used by the MCP2122 and can be used by the MCP2120. Table 2-2 shows the state of the MODE7, MODE3 and MODE2:0 signals which are used to create the clock source for the MCP2120/22 device ...

... PIC drives the MCP2120’s BAUD2:0 signals with the selected baud rate from the state of the RD2:0 signals. If the device is the MCP2122, then the PWM output frequency is determined from the state of the RD2:0 signals. This mode requires that the MCP2122’s TX and RX signals are directly connected to the MAX3238 compatible device ...
