Single Halfword Cycles

Value During Access

In normal operation, every transfer must consist of two halfword accesses.

However, to speed operation you can perform single halfword accesses.

These can be useful in performing the following tasks:

Writes to and reads from HPIC: In Table 7–7, the entire HPIC was written

to correctly after the first write. When writing the HPIC, the host does not

have to be concerned about HHWIL, nor does it have to perform two con-

secutive writes to both halfwords. Similarly, the host can choose to read

the HPIC only once, because both halves contain the same value.
