When jumpered for indirect addressing (PMA to A is open), the ENC624J600 PSP
connections simplify to the following:
Interface Signal Connections for PSP Modes 1 and 2 (Indirect Addressing)
Note that for the indirect PSP Modes 1 and 2, the ENC624J600 A8 address line is
connected to RD11/PMPCS1 (PMP address line A14). This necessitates slightly unusual
usage of the PMP module with address translation required in the application firmware.
However, this translation can be performed at compile time, resulting in no run-time
performance degradation. By not using the RF5/PMA8/U2TX pin for this address bit, the
PIC MCU’s UART2 module can still be used.
When indirect addressing is selected, the unconnected ENC624J600 A9-A14 address lines
are automatically pulled high by pull-up resistors on the PICtail Daughter Board. A fixed
application could tie these pins directly to V
