SPRS153C

The HPI8 interface consists of an 8-bit bidirectional data bus and various control signals. Sixteen-bit transfers

are accomplished in two parts with the HBIL input designating high or low byte. The host communicates with

the HPI8 through three dedicated registers — HPI address register (HPIA), HPI data register (HPID), and an

HPI control register (HPIC). The HPIA and HPID registers are only accessible by the host, and the HPIC
