79 / 90 page ![]() Data Sheet AD6676 Rev. A | Page 79 of 90 Force GPIO as Output Register Address: 0x1B1, Reset: 0x00, Name: FORCE_GPIO_OUT Table 87. Bit Descriptions for FORCE_GPIO_OUT Bits Bit Name Description Reset Access [7:4] RESERVED 0x0 RW [3:0] FORCE_GPIO_OUT Force GPIO use as an output. When used in conjunction with FORCE_GPIO, configure one or more of the pins, AGC1 to AGC4, to be used as a general purpose output or input. 0x00 RW Bit 0 = 1: use AGC1 as an output. Bit 0 = 0: use AGC1 as an input. Bit 1 = 1: use AGC2 as an output. Bit 1 = 0: use AGC2 as an input. Bit 2 = 1: use AGC3 as an output. Bit 2 = 0: use AGC3 as an input. Bit 3 = 1: use AGC4 as an output. Bit 3 = 0: use AGC4 as an input. Force GPIO Value Register Address: 0x1B2, Reset: 0x00, Name: FORCE_GPIO_VAL Table 88. Bit Descriptions for FORCE_GPIO_VAL Bits Bit Name Description Reset Access [7:4] RESERVED 0x0 RW [3:0] FORCE_GPIO_VAL Force GPIO Value. When used in conjunction with FORCE_GPIO and FORCE_GPIO_OUT, configure the state of one or more of the pins, AGC1 to AGC4, when being used as a general purpose output. 0x00 RW Bit [0]: state of AGC1 when being used as an output. Bit [1]: state of AGC2 when being used as an output. Bit [2]: state of AGC3 when being used as an output. Bit [3]: state of AGC4 when being used as an output. GPIO Output Status Register Address: 0x1B3, Reset: 0x00, Name: READ_GPO Table 89. Bit Descriptions for READ_GPO Bits Bit Name Description Reset Access [7:4] RESERVED 0x0 RW [3:0] READ_GPO Read back the status of the GPIO output bits. These are the same as the external pins, AGC1 through AGC4, if the GPIO are enabled and configured as outputs. 0x00 R GPIO Input Status Register Address: 0x1B4, Reset: 0x00, Name: READ_GPI Table 90. Bit Descriptions for READ_GPI Bits Bit Name Description Reset Access [7:4] RESERVED 0x0 RW [3:0] READ_GPI Read back the status of the GPIO input bits. These are the same as the external pins, AGC1 through AGC4, if the GPIO are enabled and configured as inputs 0x00 R |
