MEMORY_WORD_ACCESS
Table 36-7.
Starting in Run-Test/Idle, SAB data are accessed in the following way:
For any operation, the full 36 bits of the address must be provided. For write operations, 32 data
bits must be provided, or the result will be undefined. For read operations, shifting may be termi-
nated once the required number of bits have been acquired.
Table 36-8.
This instruction allows access to the entire Service Access Bus data area. Data are accessed
through a 34-bit word index, a direction bit, and 32 bits of data. This instruction is identical to
MEMORY_SIZED_ACCESS except that it always does word sized accesses. The size field is
implied, and the two lowest address bits are removed.
