The PICtail Daughter Board has the WRL/B0SEL signal connected to WRH/B1SEL, so only
16-bit word writes are possible. Writes to the high or low byte, individually, cannot be
performed.
When jumpered for indirect addressing (PMA to A is open), the ENC624J600 PSP
connections simplify to the following:
