Determines the function of the current sink
0 = LED mode
1 = Flash mode
Reset by state machine.
Selects the trigger for the flash
0 = Flash is triggered by CS1_DRIVE bit
1 = Flash is triggered from GPIO pin configured
as FLASH
This bit has no effect when
CS1_FLASH_MODE=0
Reset by state machine.
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.
Reset by state machine. Default held in metal
mask.
Determines the Flash rate
0 = Normal Operation. Once per trigger (Either
register bit or GPIO)
1 = Flash will be internally triggered every 4
seconds
Reset by state machine.
Sets duration of flash
00 = 32ms
01 = 64ms
10 = 96ms
11 = 1024ms
Reset by state machine.
Switch-off ramp duration
LED mode-
00 = instant (no ramp)
01 = 0.25s
10 = 0.5s
11 = 1s
Flash mode-
00 = instant (no ramp)
01 = 1.95ms
10 = 3.91ms
11 = 7.8ms
Reset by state machine.
