1 * Pin configuration nodes 2 3 Required properties: 4 - pio-map : array of pin configurations. Each pin is defined by 6 5 integers. The six numbers are respectively: port, pin, dir, 6 open_drain, assignment, has_irq. 7 - port : port number of the pin; 0-6 represent port A-G in UM. 8 - pin : pin number in the port. 9 - dir : direction of the pin, should encode as follows: 10 11 0 = The pin is disabled 12 1 = The pin is an output 13 2 = The pin is an input 14 3 = The pin is I/O 15 16 - open_drain : indicates the pin is normal or wired-OR: 17 18 0 = The pin is actively driven as an output 19 1 = The pin is an open-drain driver. As an output, the pin is 20 driven active-low, otherwise it is three-stated. 21 22 - assignment : function number of the pin according to the Pin Assignment 23 tables in User Manual. Each pin can have up to 4 possible functions in 24 QE and two options for CPM. 25 - has_irq : indicates if the pin is used as source of external 26 interrupts. 27 28 Example: 29 ucc_pin@1 { 30 pio-map = < 31 /* port pin dir open_drain assignment has_irq */ 32 0 3 1 0 1 0 /* TxD0 */ 33 0 4 1 0 1 0 /* TxD1 */ 34 0 5 1 0 1 0 /* TxD2 */ 35 0 6 1 0 1 0 /* TxD3 */ 36 1 6 1 0 3 0 /* TxD4 */ 37 1 7 1 0 1 0 /* TxD5 */ 38 1 9 1 0 2 0 /* TxD6 */ 39 1 a 1 0 2 0 /* TxD7 */ 40 0 9 2 0 1 0 /* RxD0 */ 41 0 a 2 0 1 0 /* RxD1 */ 42 0 b 2 0 1 0 /* RxD2 */ 43 0 c 2 0 1 0 /* RxD3 */ 44 0 d 2 0 1 0 /* RxD4 */ 45 1 1 2 0 2 0 /* RxD5 */ 46 1 0 2 0 2 0 /* RxD6 */ 47 1 4 2 0 2 0 /* RxD7 */ 48 0 7 1 0 1 0 /* TX_EN */ 49 0 8 1 0 1 0 /* TX_ER */ 50 0 f 2 0 1 0 /* RX_DV */ 51 0 10 2 0 1 0 /* RX_ER */ 52 0 0 2 0 1 0 /* RX_CLK */ 53 2 9 1 0 3 0 /* GTX_CLK - CLK10 */ 54 2 8 2 0 1 0>; /* GTX125 - CLK9 */ 55 }; 56 57
