IRQ Mask for Reference Inputs Address Bit Bit Name Description 0x020D 7 Ref AA new profile Enables IRQ for indicating that Ref AA has switched to a new profile. 6 Ref AA validated Enables IRQ for indicating that Ref AA has been validated. 5 Ref AA fault cleared Enables IRQ for indicating that Ref AA has been cleared of a previous fault. 4 Ref AA fault Enables IRQ for indicating that Ref AA has been faulted. 3 Ref A new profile Enables IRQ for indicating that Ref A has switched to a new profile. 2 Ref A validated Enables IRQ for indicating that Ref A has been validated. 1 Ref A fault cleared Enables IRQ for indicating that Ref A has been cleared of a previous fault. 0 Ref A fault Enables IRQ for indicating that Ref A has been faulted. 0x020E 7 Ref BB new profile Enables IRQ for indicating that Ref BB has switched to a new profile. 6 Ref BB validated Enables IRQ for indicating that Ref BB has been validated. 5 Ref BB fault cleared Enables IRQ for indicating that Ref BB has been cleared of a previous fault. 4 Ref BB fault Enables IRQ for indicating that Ref BB has been faulted. 3 Ref B new profile Enables IRQ for indicating that Ref B has switched to a new profile. 2 Ref B validated Enables IRQ for indicating that Ref B has been validated. 1 Ref B fault cleared Enables IRQ for indicating that Ref B has been cleared of a previous fault. 0 Ref B fault Enables IRQ for indicating that Ref B has been faulted. 0x020F [7:0] Unused Unused. 0x0210 [7:0] Unused Unused. Table 55. Watchdog Timer1 Address Bit Bit Name Description 0x0211 [7:0] Watchdog timer (expressed in ms) Watchdog timer, Bits[7:0] (default = 0x00). 0x0212 [7:0] Watchdog timer, Bits[15:8] (default = 0x00). 1 The watchdog timer is expressed in units of milliseconds (ms). The default value is 0 (disabled). Table 56. DAC Current1 Address Bit Bit Name Description 0x0213 [7:0] DAC full-scale current Full-scale current, Bits[7:0] (default = 0xFF). 0x0214 7 DAC shutdown Shut down the DAC current sources. 0 (default) = normal operation. 1 = shut down. [6:2] Unused Unused. [1:0] DAC full-scale current Full-scale current, Bits[9:8] (default = 0b01). (default current = 0x1FF, or 20.1 mA). 1 The default DAC full-scale current value is 0x01FF = 511, which equates to 20.1375 mA. |
