Data Mode	Summary	Pixel-Data Description	RC Firmware Revision
0	Error	32b (signed) co-added Error signal err[31:0]. [31:0] = error	all
1	Feedback	When servo_mode = 3: 32b (signed) SQ1 Feedback data fb[31:0]. [31:0] = sq1_fb * 212 When servo_mode != 3: 32b (signed) SQ1 Feedback from the rc? fb_const registers. These are DAC values. [31:0] = sq1_fb Note that servo_mode=3 is the normal running condition. The non-servoing form, used at times during array-auto-tune for example, is included here for completeness.	all
