HBE[1:0]

Valid

NOTES: A. During autoincrement mode, although the EHPI internally increments the memory address, reads of the HPIA register by the host

will always indicate the base address.

B. In autoincrement mode, if HBE[1:0] are used to access the data as 8-bit-wide units, the HPIA increments only following each high

byte (HBE1 low) access.

C. The falling edge of HCS must occur concurrent with or before the falling edge of HDS. The rising edge of HCS must occur

concurrent with or after the rising edge of HDS. If HDS1 and/or HDS2 are tied permanently active and HCS is used as a strobe,

the timing requirements shown for HDS apply to HCS. HRDY is always driven to the same value as its internal state.
