CSU_LOCKE:
The CSU lock interrupt enable bit (CSU_LOCKE) enables the assertion of a hardware
interrupt on INTB when the CSU lock status changes. When CSU_LOCKE is logic 1, the
hardware interrupt is enabled. When CSU_LOCKE is logic 0, the hardware interrupt is
disabled.
CSU_LOCKV:
The CSU lock status (CSU_LOCKV) indicates the current state of the CSU. When
CSU_LOCKV is logic 1, the CSU has locked on to the SYSCLK reference and is operating
normally. When CSU_LOCKV is logic 0, the CSU has not locked onto the SYSCLK reference
and is not in normal operating mode.
