---|---|---|---|---|
7:2 | 0 | W | 0h | Must write 0 |
1 | EN SYSREF DC COUPLING | R/W | 0h | This bit enables a
higher common-mode voltage input on the SYSREF signal (up to 1.6 V). 0 = Normal operation 1 = Enables a higher SYSREF common-mode voltage support |
0 | MANUAL SYSREF | R/W | 0h | The device has a
feature to apply the SYSREF signal manually through the serial interface
instead of the SYSREFP, SYSREFM pins. This application can be done by first
setting the ENABLE MANUAL SYSREF register bit, then using the MANUAL SYSREF
bit to set the SYSREF signal high or low.0 = Set SYSREF low 1 = Set SYSREF high |
