21.4 Test Descriptions

This section describes the memory dump and each type of diagnostic

test.

Processor Memory Dump

The memory dump returns the current information from specified

locations in the CTS’s processor memory. To perform a memory

dump, set the SelfTest, DevOfL, and UntOfL bits to 000 and the MD

bit to 1. Specify the starting address for the dump in the Parameter

List Length field. Then, immediately issue a RECEIVE DIAGNOSTIC

RESULTS command. Specify the number of bytes to be returned in

the Allocation Length field.

Note: If the starting address specified in the Parameter List Length

field combined with the number of bytes specified in the

Allocation Length field results in a reference to an address

greater than 97FFh, the CTS resets (wraps) the address to

0000h.

Table 21-2 indicates the values to specify for the Parameter List

Length field to reference the three types of CTS memory.

Memory address Type of memory

0toFFh Processoronchipmemory

100h to 7FFFh External RAM

8000h to 97FFh LSI hardware registers

Note: If the initiator requests more bytes than are available (that is,

more than 9064h bytes), the CTS will send all available bytes

and then terminate. This is not an error.
