92 / 116 page  AD9554 Data Sheet Rev. D | Page 92 of 116 IRQ CLEARING (REGISTER 0x0A05 TO REGISTER 0x0A14) The IRQ clearing registers are identical in format to the IRQ monitor registers (Register 0x0D08 to Register 0x0A14). When set to Logic 1, an IRQ clearing bit resets the corresponding IRQ monitor bit, thereby cancelling the interrupt request for the indicated event. The IRQ clearing registers are autoclearing. Table 103. Clear IRQ Groups Address Bits Bit Name Description 0x0A05 7 Clear watchdog timer Clears watchdog timer alert 6 Reserved Reserved 5 Clear DPLL_3 IRQs Clears all IRQs associated with DPLL_3 4 Clear DPLL_2 IRQs Clears all IRQs associated with DPLL_2 3 Clear DPLL_1 IRQs Clears all IRQs associated with DPLL_1 2 Clear DPLL_0 IRQs Clears all IRQs associated with DPLL_0 1 Clear common IRQs Clears all IRQs associated with common IRQ group 0 Clear all IRQs Clears all IRQs Table 104. IRQ Clearing for SYSCLK and EEPROM Address Bits Bit Name Description 0x0A06 7 SYSCLK unlocked Clears IRQ indicating a SYSCLK PLL state transition from locked to unlocked 6 SYSCLK stable Clears IRQ indicating that SYSCLK stability time has expired and that the SYSCLK PLL is considered to be stable 5 SYSCLK locked Clears IRQ indicating a SYSCLK PLL state transition from unlocked to locked 4 SYSCLK cal ended Clears IRQ indicating a SYSCLK PLL calibration has ended 3 SYSCLK cal started Clears IRQ indicating a SYSCLK PLL calibration has started 2 Watchdog timer Clears IRQ indicating expiration of the watchdog timer 1 EEPROM fault Clears IRQ indicating a fault during an EEPROM upload or download operation 0 EEPROM complete Clears IRQ indicating successful completion of an EEPROM upload or download operation Table 105. IRQ Clearing for Reference Inputs Address Bits Bit Name Description 0x0A07 7 Reserved Reserved 6 REFB validated Clears IRQ indicating that REFB has been validated 5 REFB fault cleared Clears IRQ indicating that REFB has been cleared of a previous fault 4 REFB fault Clears IRQ indicating that REFB has been faulted 3 Reserved Reserved 2 REFA validated Clears IRQ indicating that REFA has been validated 1 REFA fault cleared Clears IRQ indicating that REFA has been cleared of a previous fault 0 REFA fault Clears IRQ indicating that REFA has been faulted 0x0A08 7 Reserved Reserved 6 REFD validated Clears IRQ indicating that REFD has been validated 5 REFD fault cleared Clears IRQ indicating that REFD has been cleared of a previous fault 4 REFD fault Clears IRQ indicating that REFD has been faulted 3 Reserved Reserved 2 REFC validated Clears IRQ indicating that REFC has been validated 1 REFC fault cleared Clears IRQ indicating that REFC has been cleared of a previous fault 0 REFC fault Clears IRQ indicating that REFC has been faulted |
