4-2-8 Operation Commands
Operation commands are used to RUN and STOP, to move to setting area 1,
and other similar operations. As shown in the following table, operation com-
mands are executed using a combination of command codes, related infor-
mation, and strobes.
Note (1) Operations apply to all channels.
(2) The channel is specified.
0: Channel 1; 1: Channel 2; 2: Channel 3; 3: Channel 4; F: All channels
(3) The write mode defaults are in backup mode.
Operation commands are created as shown in the following diagram.
Bit 15 is strobe 2 and bit 14 is strobe 1. A logical OR is taken between the two
leftmost bits of the command code and bits 15 and 14, and the result is
attached as the strobe to the operation command. The command code for
E5AR/ER operation commands is 0
@ hex, so when the logical OR is 8 @ hex,
the strobe is ON.
