Determines the function of the current
sink
0 = LED mode
1 = Flash mode
Selects the trigger in Flash mode.
0 = Flash triggered by CS1_DRIVE bit
1 = Flash triggered from GPIO pin
This bit has no effect when
CS1_FLASH_MODE=0
Enables the current sink ISINKA
LED mode-
0 = disable LED
1 = enabled LED
FLASH mode-
Register bit used to trigger the flash, if
CS1_TRIGSRC is set to 0. Flash is
started when the bit goes high, it is then
reset at the end of the flash duration.
Duration is determined by
CS1_FLASH_DUR. This bit has no effect
if CS1_TRIGSRC is set to 1.
Determines the Flash rate
0 = Normal Operation. Once per trigger
(Either register bit or GPIO)
1 = Flash will be internally triggered
every 4 second
Sets duration of flash
00 = 32ms
01 = 64ms
10 = 96ms
11 = 1024ms
configured as FLASH
