PRODUCTION DATA
| CMD Address | DAh |
| Write Transaction: | NA |
| Read Transaction: | Read Block |
| Format: | Unsigned Binary (14 bytes) |
| Phased: | No |
| NVM Back-up: | No |
READ_ALL provides for a 14-byte BLOCK read of STATUS_WORD and telemetry values to improve bus usage for poling by combining multiple READ functions into a single command, eliminating the need for multiple address and command code bytes.
