This register configures the operation of CSTR blocks #1 through #4.
LOCKE
The CSU lock interrupt enable bit (LOCKE) controls the contribution of CSU lock state
interrupts by the CSTR to the device interrupt INTB. When LOCKE is high, INTB is asserted
low when the CSU lock state changes. Interrupts due to CSU lock state are masked when
LOCKE is set low.
LOCKV
The CSU lock status bit (LOCKV) indicates whether the clock synthesis unit has successfully
locked with the system clock. LOCKV is set low when the CSU has not successfully locked
with the reference clock. LOCKV is set high if when the CSU has locked with the reference
clock.
