HPI*-16 Multiplexed Read Accesses Values
NOTES:
EX_ADDR[2:1]
1. The address phase parameter (T1) must be set to a minimum value of 2. This value allows three T clocks
2. The data setup phase parameter (T2) must be set to a minimum value of 2. This value allows three T
3. The data strobe phase parameter (T3) must be set to a minimum value of 1. This value allows two T
4. Setting the recovery phase parameter (T5) will adjust the duration between successive accesses on the
5. HRDY can be asserted by the DSP at any point in the access. The interface will not leave states T1 or T3
6. One cycle is the period of the Expansion Bus clock.
7. Timing was designed for a system load between 5pF and 60pF for high drive setting
