These two (2) GPIO bits are connected to the U38 MSP430 system controller for general purpose signaling or communications between the Zynq UltraScale+ RFSoC and the MSP430 system controller. These signals are level-shifted by TSX0108E U37. The connections between the U38 system controller and the ZU49DR RFSoC are listed in following table.
ZU49DR U1 Pin | Net Name | MSP430 U38 | |
---|---|---|---|
Pin Name | Pin Number | ||
G32 | MIO38_PS_GPIO1 | P1_6 | 19 |
AU26 | MIO13_PS_GPIO2 | P1_7 | 20 |
