4.1.14 - Miscellaneous [UE9 Datasheet]

The following are special channels, used with the get/put config IOTypes, to read/write the calibration memory and user memory:

LJ_chCAL_CONSTANTS    // x1 points to an array with 128 doubles.
LJ_chUSER_MEM    // x1 points to an array with 1024 bytes.


LJ_chCAL_CONSTANTS makes 8 calls to the low-level ReadMem or
EraseMem/WriteMem functions to do a consecutive read or erase/write of
the 8x 128-byte
blocks of calibration memory (blocks 0-7), or 1024 bytes total.  Those
bytes represent 128x 64-bit fixed point values in hardware, but are
passed to/from the
UD as 128 doubles.

LJ_chUSER_MEM makes 8 calls to the low-level ReadMem or
EraseMem/WriteMem functions to do a consecutive read or erase/write of
the 8x 128-byte
blocks of user memory (blocks 8-15), or 1024 bytes total. 

For more information, see the low-level descriptions for ReadMem, WriteMem, EraseMem, and see the Memory example in the VC6_LJUD archive.
