21 / 44 page  Data Sheet ADP5586 Rev. 0 | Page 21 of 44 DETAILED REGISTER DESCRIPTIONS Note that all registers default to 0000 0000, unless otherwise specified. ID, Register 0x00 Default: 0011 XXXX (where X = don’t care) Table 8. ID Bit Descriptions Bits Bit Name Access Description [7:4] MAN_ID Read only Manufacturer ID, default = 0011 [3:0] REV_ID Read only Revision ID INT_STATUS, Register 0x01 Table 9. INT_STATUS Bit Descriptions Bits Bit Name Access Description1 [7:5] Reserved Reserved Reserved. 4 LOGIC_INT Read/write 0 = no interrupt. 1 = interrupt due to a general logic condition. 3 Reserved Reserved Reserved. 2 OVERFLOW_INT Read/write 0 = no interrupt. 1 = interrupt due to an overflow condition. 1 GPI_INT Read/write This bit is not set by a GPI that has been configured to update the FIFO and event count. This bit cannot be cleared until all GPI_x_INT bits are cleared. 0 = no interrupt. 1 = interrupt due to a general GPI condition. 0 EVENT_INT Read/write 0 = no interrupt. 1 = interrupt due to key event (press/release), GPI event (GPI programmed for FIFO updates), or logic event (programmed for FIFO updates). 1 Interrupt bits are cleared by writing a 1 to the flag; writing a 0 or reading the flag has no effect. Status, Register 0x02 Table 10. Status Bit Descriptions Bits Bit Name Access Description 7 Reserved Reserved Reserved. 6 LOGIC_STAT Read only 0 = output from logic block (LY) is low. 1 = output from logic block (LY) is high. 5 Reserved Reserved Reserved. [4:0] EC[4:0] Read only Event count value. Indicates how many events are currently stored on the FIFO. FIFO_1, Register 0x03 Table 11. FIFO_1 Bit Descriptions Bits Bit Name Access Description 7 EVENT1_STATE Read only This bit represents the state of the event that is recorded in the EVENT1_IDENTIFIER[6:0] bits. For key events from Event 1 to Event 36, use the following settings: 1 = key is pressed. 0 = key is released. For GPI and logic events from Event 37 to Event 48, use the following settings: 1 = GPI/logic is active. 0 = GPI/logic is inactive. Active and inactive states for Event 37 to Event 48 are programmable. [6:0] EVENT1_IDENTIFIER[6:0] Read only Contains the event identifier for the pin. See Table 12 for event decoding information. |
