[Figure 2, callout 18]
I2C bus I2C1 connects RFSoC U1 PS Bank 500, PL bank 89, and system controller U38 to two
I2C switches (TCA9548A U20 and U22). These I2C1 connecons enable I2C communicaons
with various I2C capable target devices. TCA9548A U20 is pin-strapped to respond to I2C
address 0x74. TCA9548A U22 is pin-strapped to respond to I2C address 0x75.
