CP2108 Channel 3 MSP430 UART Interface
The CP2108 Channel 3 MSP430 UART interface circuit is shown in
. The
connections from MSP430 U41 to CP2108 U40 via TSX0104E level shifter U53 are listed in
.
GPIO (MIO 13, 38)
These two (2) GPIO bits are connected to the U41 MSP430 system controller for general
purpose signaling or communications between the Zynq Ult MPSoC device and the
MSP430 system controller. These signals are level-shifted by TSX0108E U141. The
connections between the U41 system controller and the XCZU9EG MPSoC are listed in
.
