MEMORY_SERVICE
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 36-5.
This instruction allows access to registers in an optional Memory Service unit. Memory Service
registers are addressed by their register index, as listed in the Memory Service documentation.
The 7-bit register index and a read/write control bit, and the 32-bit data is accessed through the
JTAG port.
The Memory Service unit may offer features such as CRC calculation of memory, debug trace
support, and test features. Please refer to the Memory Service Unit documentation and the part
specific documentation for details.
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_SERVICE instruction is selected, and
toggles between address and data mode each time a data scan completes with the busy bit
cleared.
Starting in Run-Test/Idle, Memory Service registers are accessed in the following way:
