† Host-only mode timings apply for read accesses to HPIC or HPIA, write accesses to BOB, and resetting DSPINT or HINT to 0 in shared-access
mode. HRDY does not go low for these accesses.
‡ Shared-access mode timings will be met automatically if HRDY is used.
NOTES:
5. SAM = shared-access mode, HOM = host-only mode
HAD stands for HCNTRL0, HCNTRL1, and HR/W.
HDS refers to either HDS1 or HDS2.
DS refers to the logical OR of HCS and HDS.
6. On host read accesses to the HPI, the setup time of HD before DS rising edge depends on the host waveforms and cannot be
specified here.
