150 / 363 page  WM8994 150 Rev 4.6 REGISTER ADDRESS BIT LABEL DEFAULT DESCRIPTION R1794 (0701h) GPIO3 to R1802 (070Ah) GPIO11 15 GPn_DIR 1 GPIOn Pin Direction 0 = Output 1 = Input 14 GPn_PU 0 GPIOn Pull-Up Enable 0 = Disabled 1 = Enabled 13 GPn_PD 1 GPIOn Pull-Down Enable 0 = Disabled 1 = Enabled 10 GPn_POL 0 GPIOn Polarity Select 0 = Non-inverted (Active High) 1 = Inverted (Active Low) 9 GPn_OP_CFG 0 GPIOn Output Configuration 0 = CMOS 1 = Open Drain 8 GPn_DB 1 GPIOn Input De-bounce 0 = Disabled 1 = Enabled 6 GPn_LVL 0 GPIOn level. Write to this bit to set a GPIO output. Read from this bit to read GPIO input level. For output functions only, when GPn_POL is set, the register contains the opposite logic level to the external pin. 4:0 GPn_FN [4:0] 0001 GPIOn Pin Function (see Table 81 for details) Note: n is a number between 3 and 11 that identifies the individual GPIO.
