(1) HSTROBE refers to the following logical operation on HCS, HDS1, and HDS2: [NOT(HDS1 XOR HDS2)] OR HCS.
(2) M = SYSCLK3 period = (CPU clock frequency)/4 in ns. For example, when running parts at 1 GHz, use M = 4 ns.
(3) Select signals include: HCNTL[1:0], HR/W. For HPI16 mode only, select signals also includes HHWIL.
