Table 4-11. Display Format Control Byte Description (10h)

BYTE	BIT	VALUE	DESCRIPTION
3	0		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.
3	1		Reserved.
3	2		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.
3	3	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.
3	4	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.
3	5-7		Table 4-13 defines the Display Mode Selection bits.

4-3.4.2 Display Data (10h)

The 16 bytes of DISPLAY data consists of two eight-byte messages. See Table 4-12, Table 4-13 and Table 4-8 on page 4-10. If the Parameter List Length is set to 0, no action is performed and it is not considered an error.

Table 4-12. DISPLAY Parameter (10h)

					BITS
BYTES	7	6	5	4		3	2	1	0
0-7				First Half Message
8-15				Second Half Message

Note: All bytes should not be set to spaces, because this would appear as a MTU powered down state.
