5 PRELIMINARY INFORMATION
(1) Changing the bank when using the A Series master module
When using the A series master module (AJ61BT11/A1SJ61BT11), the master
station's automatic transmission/reception buffer will be "bank 1".
Thus, create a program that changes to "bank 1"when reading or writing to the
transmission/reception buffer, and returns to "bank 0" when the reading/writing is
completed.
When using the dedicated commands RIWT/RIRD/RISEND/RIRCV, the bank will
be changed automatically by the dedicated commands, so the user does not
need to change the bank.
Refer to section 5.2 for details on changing the bank.
