(13) Output data to slave addresses 4B to 31B (Buffer memory address
39H to 3FH : Un\G57 to Un\G63)
The output data of the AS-i Ver. 2.11-compatible (System B) slaves are stored.
The values stored into the areas corresponding to the non-connected and nondetected slaves are invalid (ignored).

By turning ON the bit corresponding to the slave address to be communicated
with and turning ON Y13, the contents of this buffer memory are registered to the
QJ71AS92 and reflected on the projected slave list (LPS (for read)) (buffer
memory addresses: 19H to 1CH).
(Related item: Section 4.5 (2))
TIP
• The projected slave list (LPS (for write)) is handled as a 64-bit length in the
QJ71AS92. Therefore, if data is written to only the buffer memory address 49H,
the contents of the buffer memory address 4AH to 4CH are also made valid as
data.
• When communicating with the slave that has been judged as ready for
communication in the active slave list (LAS) (buffer memory addresses: 15H to
18H), easy registration of the projected slave list (LPS (for read)) and configuration
are enabled by using the command buffer <request> 201H.
