5 td(HSTBL-HRDYV) Delay time,
UHPI_HSTROBE low to UHPI_HRDY valid		 For HPI Write, UHPI_HRDY can go high (not ready) for these HPI Write conditions; otherwise, UHPI_HRDY stays low (ready):
Case 1: Back-to-back HPIA writes (can be either first or second half-word)
Case 2: HPIA write following a PREFETCH command (can be either first or second half-word)
Case 3: HPID write when FIFO is full or flushing (can be either first or second half-word)
Case 4: HPIA write and Write FIFO not empty

For HPI Read, UHPI_HRDY can go high (not ready) for these HPI Read conditions:
Case 1: HPID read (with auto-increment) and data not in Read FIFO (can only happen to first half-word of HPID access)
Case 2: First half-word access of HPID Read without auto-increment
For HPI Read, UHPI_HRDY stays low (ready) for these HPI Read conditions:
Case 1: HPID read with auto-increment and data is already in Read FIFO (applies to either half-word of HPID access)
Case 2: HPID read without auto-increment and data is already in Read FIFO (always applies to second half-word of HPID access)

(2) UHPI_HSTROBE refers to the following logical operation on UHPI_HCS, UHPI_HDS1, and UHPI_HDS2: [NOT(UHPI_HDS1 XOR UHPI_HDS2)] OR UHPI_HCS.
(3) By design, whenever UHPI_HCS is driven inactive (high), HPI will drive UHPI_HRDY active (low).
