The Data Format bit describes the type of data contained in bytes 0 through 15.
0 If this bit is 0, the data in bytes 0 through 15 is in EBCDIC format.
1 If this bit is 1, the data in bytes 0 through 15 is in ASCII format.
Reserved.
The Half Msg bit selects which half of the message is to be displayed. This bit is valid
only when the Display length bit is set to zero.
0 When the Half Msg bit is set to zero, the first half of the message (bytes 0 to 7) is dis-
played.
1 When the Half Msg bit is set to one, the second half of the message (bytes 8 to 15) is
displayed.
0 When the Flash bit is set to zero, the display does not flash.
1 A Flash bit set to one causes the display to flash.
0 When the Display Length bit is set to zero, only 8 bytes are displayed. Whether bytes 0
to 7 or bytes 8 to 15 are displayed is selected by bit 2. If bit 2 is set to 0b then bytes 0
through 7 are displayed. If bit 2 is set to 1b bytes 8 to 15 are displayed.
1 When the display length bit is set to one, bytes 0 to 7 and bytes 8 to 15 are displayed
alternately. Bits 2-3 are ignored for this selection.
Table 4-13 defines the Display Mode Selection bits.
