Returns block data for all keys’ references.
The low order byte is returned first.
Returns block data for all keys’ signal deltas from refs,
{reference - signal}; Unsigned binary bytes, in range 0..255.
Last return byte is CRC-8 of cmmd + return data
Last return byte is CRC-8 of cmmd + return data
Dump of fixed length ‘nn’ followed by CRC-16
CRC is same as CRC at end of Setups block load.

This CRC is the same as the CRC at the end of Setups block load.

Diagnostic code for factory use. The low order byte is returned first.
