GPIO control Register Addr: 1Eh GPIO control This register controls GPIO3 and GPIO31 pin functions. Bit Bit Name Default Access Description 1:0 gpio1_mode 00 R/W Defines the direction for pin ALS/GPIO1 00 Input only 01 Output (push and pull) 10 Output (open drain, only push; only NMOS is active) 11 Output (open drain, only pull; only PMOS is active) 3:2 gpio1_pulls 11 R/W Adds the following pullup/pulldown to pin ALS/GPIO1; this is independent of setting of bits gpio1_mode 00 None 01 Pulldown 10 Pullup 11 ADC input (gpio1_mode = XX); recommended for analog signals 5:4 gpio2_mode 00 R/W Defines the direction for pin GPIO2 00 Input only 01 Output (push and pull) 10 Output (open drain, only push; only NMOS is active) 11 Output (open drain, only pull; only PMOS is active) 7:6 gpio2_pulls 01 R/W Adds the following pullup/pulldown to pin GPIO2; this is independent of setting of bits gpio2_mode 00 None 01 Pulldown 10 Pullup 11 ADC input (gpio2_mode = XX); recommended for analog signals Table 83. GPIO control 3 Register Addr: 1Fh GPIO control 3 This register enables low current mode for GPIO3s. Bit Bit Name Default Access Description 1:0 gpio3_mode 00 R/W Defines the direction for pin GPIO3 00 Input only 01 Output (push and pull) 10 Output (open drain, only push; only NMOS is active) 11 Output (open drain, only pull; only PMOS is active) |
