13. “2 CHANNEL WRT 1ST” means “second channel with respect to first;” in other words, Channel 2 lags Channel 1 by the degrees specified in this
column. For example, 90° means Channel 2 lags Channel 1 by 90°; -60° means Channel 2 leads Channel 1 by 60°.
14. “VMON1” means that the pin is tied to the VMON1 pin of the same module.
“Divider” means that there is a resistor divider from VOUT to SGND; refer to Figure 24.
“1kΩ” means that there is a 1kΩ resistor connecting the pin to SGND; refer to Figure 22.
