channel 2

An overcurrent event can be simulated using SOVCx.

If SOVCx = 1, the corresponding overcurrent error bit

OVCx will be set to 1, the error will be signaled at

NCHK and the corresponding laser channel will be dis-

abled. The overcurrent error will remain forced until

SOVCx = 0.

SOVC1

Addr. 0x1D; bit 5

R/W 0

No Overcurrent event at channel 1 is simulated

Overcurrent event at channel 1 simulated

SOVC2

Addr. 0x1D; bit 6

R/W 0

No overcurrent event at channel 2 is simulated
