When jumpered for indirect addressing (PMA to AD is open), the ENC624J600 PSP
connections simplify to the following:

Like indirect PSP Modes 1 and 2, the indirect PSP Modes 5 and 6 have the ENC624J600
Address Line 8 connected to RD11/PMPCS1 instead of RF5/PMA8/U2TX to allow the
UART2 module to be used concurrently.
Of all possible parallel combinations, PSP Modes 5 and 6, with indirect addressing, use the
least I/O pins, but still provide very respectable performance. With minimal I/O pins used, it
is the least likely combination to have multiplexed board and processor features causing
unexpected behavior. It, therefore, should be the starting point when evaluating the
ENC624J600 device’s parallel interface for the first time. When using PSP Modes 5 and 6,
the ENC624J600 behavior is representative of the lower pin count ENC424J600, which only
supports SPI and PSP Modes 5 and 6.
