NOTES:
1. The HRDY output is always high when the HCS input is high, regardless of DS timings.
2. This timing applies when writing a one to the DSPINT bit or HINT bit of the HPIC register. All other writes to the HPIC occur
asynchronously, and do not cause HRDY to be deasserted.
DS refers to the logical OR of HCS, HDS1, and HDS2.
HDx refers to any of the HPI data bus pins (HD0, HD1, HD2, etc.).
§ DMAC stands for direct memory access (DMA) controller. The HPI8 shares the internal DMA bus with the DMAC, thus HPI8 access times are
affected by DMAC activity.
GPIO refers to the HD pins when they are configured as general-purpose input/outputs.
