Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7:6 | Reserved | R | 0h | Reserved. Do not write any value other than reset value. |
5:2 | GPIO1 SEL | R/W | 0000h | 0000: GPIO1 disabled (input and output buffers powered down)
0001: GPIO1 is in input mode (can be used as secondary BCLK input, secondary WCLK input, or in ClockGen block) 0010: GPIO1 is used as general-purpose input (GPI) 0011: GPIO1 output = general-purpose output 0100: GPIO1 output = CLKOUT output (source determined by CDIV_CLKIN_REG; page 0, register 25) 0101: GPIO1 output = INT1 output 0110: GPIO1 output = INT2 output 0111: Reserved. Do not use. 1000: GPIO1 output = secondary BCLK output for codec interface 1001: GPIO1 output = secondary WCLK output for codec interface 1010: DMDIN output = ADC_MOD_CLK output for the digital microphone 1011–1111: Reserved. Do not use. |
1 | GPIO1 IN BUF VAL | R | 0h | GPIO1 input buffer value |
0 | GPIO1 VAL | R/W | 0h | 0: GPIO1 value = 0 when bits 5:2 are programmed to 0011 (general-purpose output)
1: GPIO1 value = 1 when bits 5:2 are programmed to 0011 (general-purpose output) |
