MEMORY_SIZED_ACCESS
For any operation, the full 7 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 27-17. MEMORY_SERVICE Details
This instruction allows access to the entire Service Access Bus data area. Data is accessed
through a 36-bit byte index, a 2-bit size, a direction bit, and 8, 16, or 32 bits of data. Not all units
mapped on the SAB bus may support all sizes of accesses, e.g., some may only support word
accesses.
The data register is alternately interpreted by the SAB as an address register and a data regis-
ter. The SAB starts in address mode after the MEMORY_SIZED_ACCESS instruction is
selected, and toggles between address and data mode each time a data scan completes with
the busy bit cleared.
