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.).
§GPIO refers to the HD pins when they are configured as general-purpose input/outputs.
HAD refers to HCNTL0, HCNTL1, and H/RW.
#When the HAS signal is used to latch the control signals, this timing refers to the falling edge of the HAS signal. Otherwise, when HAS is not used
(always high), this timing refers to the falling edge of DS.
