The diagnostic interface provides direct memory manipulation through specialized commands that enable precise hardware-level testing and validation:

|+ '''Memory Control and Manipulation Commands'''
|-
! Command !! Function !! Technical Implementation
|-
| '''*L<address>''' || Set memory location pointer || Establishes base address for subsequent memory operations, address specified in hexadecimal
|-
| '''*B<count>''' || Set byte count for operations || Specifies number of bytes for write operations, read operations ignore this and always return 4 bytes
|-
| '''*D<data>''' || Deposit/write data to memory || Writes specified hexadecimal data to current memory location, respects byte count parameter
|-
| '''*M''' || Memory read command || Reads 4 bytes from current location and auto-increments address pointer, ignores byte count setting
|-
| '''*G<address>''' || Go/execute code at address || Launches code execution at specified memory address for dynamic testing
|-
| '''*G''' || Continue execution || Resumes execution from current program counter location
|-
| '''*R''' || Read/status command || Returns diagnostic status information and memory configuration data
