| 5 | td(HSTBL-HRDYV) | Delay time, HSTROBE low to HRDY valid | For HPI Write, HRDY can go high (not ready) for these HPI Write conditions; otherwise, 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, 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, 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) Case 3: HPIC or HPIA read (applies to either half-word access) |

| 15 | td(HSTBL-HDV) | Delay time, HSTROBE low to HD valid | For HPI Read. Applies to conditions where data is already residing in HPID/FIFO:
Case 1: HPIC or HPIA read Case 2: First half-word of HPID read with auto-increment and data is already in Read FIFO Case 3: Second half-word of HPID read with or without auto-increment |

| 18 | td(HSTBH-HRDYV) | Delay time, HSTROBE high to HRDY valid | For HPI Write, HRDY can go high (not ready) for these HPI Write conditions; otherwise, HRDY stays low (ready):
Case 1: HPID write when Write FIFO is full (can happen to either half-word) Case 2: HPIA write (can happen to either half-word) Case 3: HPID write without auto-increment (only happens to second half-word) |
