Table 7–15 and Table 7–16 summarize a host data write with autoincrement

for HWOB = 1 and HWOB = 0, respectively. These examples are identical to

the ones in section 7.4.4, except for the HCNTL[1:0] value and a subsequent

write of 33h to the most significant byte of the word at address 8000 1238h.

The increment occurs on the rising edge of HSTROBE on the next HPID write

access. If the next access is an HPIA or HPIC access or an HPID read, the

autoincrement does not occur.
