Take special care to minimize noise levels on the VDDA and VSSA pins.
When using Wired-OR mode on the SPI or the IRQx pins, the user must provide an external pull-up device.
Designs that utilize the TRST pin for JTAG port or Enhance OnCE module functionality (such as
development or debugging systems) should allow a means to assert TRST whenever RESET is asserted, as
well as a means to assert TRST independently of RESET. Designs that do not require debugging
functionality, such as consumer products, should tie these pins together.
The internal POR (Power on Reset) will reset the part at power on with reset asserted or pulled high but
requires that TRST be asserted at power on.
