This register provides for control of the nominal APC setpoint and management of interrupts by the end-user. APCSEL[1:0]
select which of the APC setpoint registers, APCSET0, APCSET1, or APCSET2 are used as the nominal automatic power
control setpoint. Similarly, MODSEL[1:0] select which of MODSET0, MODSET1, or MODSET2 are used to select the
modulation level of the laser.
IE must be set for any host interrupts to occur via the /INT pin. If IE is set while /INT is asserted, /INT will be de-asserted
immediately.
PORS is always set high by any power-on reset event. If PORM is high, the power-on event will also generate a host interrupt.
PORS will be cleared to zero and the interrupt output de-asserted when USRCTL is read by the host.
If PORM is set following the setting of PORS, PORS will remain set, and /INT will be asserted immediately. /INT will not be de-
asserted until USRCTL is read by the host.
PORM, IE, APCSEL, and MODSEL are non-volatile and will be maintained through power and reset cycles.
