7.6.2 I/O restriction to other features
Caution: Due to the sharing of some I/Os of STM32U575AII6Q by multiple peripherals, the following limitations apply in
using the TRACE features:
•
The TRACE D0/D1/D3 function cannot be operated simultaneously with the SD card function.
• The TRACE D3 function cannot be operated simultaneously with the STMod+ (SPI) function.
• The TRACE JTDI function cannot be operated simultaneously with the UCPD function.
• The TRACE JTDO/SWO function cannot be operated simultaneously with the audio MEMS function.
• The TRACE JTRSTN function cannot be operated simultaneously with the COMP2 interface.
