120 / 233 page  KSZ9567R DS00002329E-page 120 2022 Microchip Technology Inc. and its subsidiaries 5.1.6.15 GPIO Status Monitor 0 Register 5.1.6.16 GPIO Status Monitor 1 Register This register provides the interrupt status for the trigger output unit and timestamp units used with the GPIO. The GPIO pin Output Trigger and Timestamp Unit interrupt status bit in the Global Interrupt Status Register is the OR of the status bits in this register. Address: 0x0524 - 0x0527 Size: 32 bits Bits Description Type Default 31:19 RESERVED RO 0x000 18:16 Event Trigger Output Error (TRIGGER_ERROR) (Bit 18 = Trigger Unit 2, Bit 17 = Trigger Unit 1, Bit 16 = Trigger Unit 0) 1 = The event trigger time is set earlier than the system time clock when the TRIGGER_NOTIFY bit is set to “1” in the Trigger Output Unit Control 1 Regis- ter and will generate an interrupt to the host. This bit can be cleared by reset- ting the TRIGGER_EN bit to “0” in the Timestamp Control and Status Register. 0 = No event trigger error. R/W1C 000b 15:3 RESERVED RO 0x000 2:0 Event Trigger Output Unit Done (TRIGGER_DONE) (Bit 2 = Trigger Unit 2, Bit 1 = Trigger Unit 1, Bit 0 = Trigger Unit 0) 1 = The event trigger output unit has been generated when the TRIG- GER_NOTIFY bit is set to “1” in the Trigger Output Unit Control 1 Register (write “1” to clear this bit) and will generate an interrupt to the host. 0 = Event trigger output unit not done. R/W1C 000b Address: 0x0528 - 0x052B Size: 32 bits Bits Description Type Default 31:19 RESERVED RO 0x0000 18:16 Trigger Output Unit Interrupt Status (Bit 18 = Trigger Unit 2, Bit 17 = Trigger Unit 1, Bit 16 = Trigger Unit 0) These three bits provide the interrupt status for the three Trigger Output Units. These interrupts are enabled by setting the TRIGGER_NOTIFY bit in the Trigger Output Unit Control 1 Register. This is done separately for each TOU. Refer to the GPIO Status Monitor 0 Register for the Trigger Output Unit status details. 1 = Interrupt detected 0 = No interrupt R/WC 000b 15:2 RESERVED RO 0x0000 |
