Current_Mon_Timer_y[7:0]

Current_Mon_Timer_x[7:0]

Current_Mon_Timer_y[7:0] $00 $00 $00 Channel y current monitor timer value corresponding to SPI command

DCMTSxy.

Set to default (cleared) on SSM_RESET or when a new deployment starts on

channel y. Increments each 16 µs while deployment current exceeds monitor

threshold on channel y

Current_Mon_Timer_x[7:0] $00 $00 $00 Channel x current monitor timer value corresponding to SPI command

DCMTSxy.

Set to default (cleared) on SSM_RESET or when a new deployment starts on

channel x. Increments each 16 µs while deployment current exceeds monitor

threshold on channel y
