The bits are defined as follows:
• SGN = Sign bit in 2’s complement format.
• EC = Enable Channel.
• NU = Not used. Bit must be set to 0.
• EHI = Enable Output Channel Interrupt on High Clamp Alarm.
(1)
• ELI = Enable Output Channel Interrupt on Low Clamp Alarm.
(1)
• LC = Latch Low/High Clamp and Under/Over Range Alarm.
• ER = Enable Ramping.
(1)
• FM = Enable Fault Alternate Output State mode.
(1)
• PM = Enable Program/Idle Alternate Output State mode.
(1)
• PFE = Enable Program/Idle to Fault Alternate Output State mode.
(1)
• Format Chx = Output Data Format Select.
• Type/Range Sel Chx = Output Type/Range Select.
• Fault Value Channel x = Provides the ability to configure the Fault mode
alternate output value.
(1)
• Program (Idle) Value Channel x = Provides the ability to configure the
Program (Idle) alternate output value.
(1)
• Clamp High Data Value Channel x = Provides the ability to configure the
output high clamp value.
• Clamp Low Data Value Channel x = Provides the ability to configure the
output low clamp value.
• Ramp Rate Channel x = Provides the ability to configure the Ramp
Rate.
