General Purpose I/O (GPIO)
7.3.2.1.8 GPS GPIO Output-Only Data Value Out Register —MBAR + 0x0B1C
Bit Name Description
0:7 ETHR Individual bits to enable each Output Only GPIO pin—all reside on the Ethernet port.
bit 0 controls GPIO_ETHO_7 (ETH_7 pin)
bit 1 controls GPIO_ETHO_6 (ETH_6 pin)
bit 2 controls GPIO_ETHO_5 (ETH_5 pin)
bit 3 controls GPIO_ETHO_4 (ETH_4 pin)
bit 4 controls GPIO_ETHO_3 (ETH_3 pin)
bit 5 controls GPIO_ETHO_2 (ETH_2 pin)
bit 6 controls GPIO_ETHO_1 (ETH_1 pin)
bit 7 controls GPIO_ETHO_0 (ETH_0 pin)
0 = Disabled for GPIO use (default)
1 = Enabled for GPIO use
8 :11 — Reserved
12:15 I2C Individual bits to enable each Output Only GPIO pin—all reside on the I2C ports.
bit 12 controls I2C2_CLK (I2C_2 pin)
bit 13 controls I2C2_IO (I2C_3 pin)
bit 14 controls I2C1_CLK (I2C_0 pin)
bit 15 controls I2C1_IO (I2C_1 pin)
0 = Disabled for GPIO use (default)
1 = Enabled for GPIO use
This bits can be used to toggle the clock (SCL) and data (SDA) lines of the I2C interface.
