[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 connections enable I2C communications
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.
