PMC MIO[44:45] I2C1 Bus
[Figure 3, callout 11]
Bus I2C1 connects the XCVC1902 U1 PS bank 501, and the XCZU4EG system controller U125
PS bank 501 to two I2C switches (TCA9548A U35 and U214). These I2C1 connections enable
I2C communications with other I2C capable target devices. TCA9548A U35 is pin-strapped to
respond to I2C address 0x74. TCA9548A U214 is pin-strapped to respond to I2C address 0x75.
The following figure shows the I2C1 bus connectivity detailed in the first two tables below. The
I2C0 target device I2C addresses are listed in the third table.
