5.2.1 About bank changing of the A series master module
When using the R2, the master station's automatic update buffer or
transmission/reception buffer is used.
With the A Series master module (AJ61BT11/A1SJ61BT11), the automatic update
buffer and transmission/reception buffer are divided with banks. When accessing these
buffers, the bank must be changed.
POINT
When using dedicated commands (RITO, RIFR, RIRD, RIWT, RISEND,
RIRCV), the bank is changed with the dedicated commands, and does not need
to be changed by the user.
After changing to bank 1 or bank 2 and then reading or writing, return to bank 0.
The information such as RX, RY, RWw or RWr will not be updated unless the
bank is changed to bank 0.
