Register 022H, 026H: CSTR #1 – 2* Interrupt Indication
LOCKI
Bit
Bit 31-1
Bit 0
The CSU lock interrupt status bit (LOCKI) reports and acknowledges changes in the CSU
lock state. LOCKI is set high when the CSU achieves lock with the reference clock or loses
its lock to the reference clock. LOCKI is cleared on a read to this register when WCIMODE
is logic 0. LOCKI is cleared on a write (of any value) to this register when WCIMODE is
logic one. INTB is asserted low when both LOCKE and LOCKI are high. If LOCKE is
asserted, LOCKI must be cleared before INTB will be reasserted.
