VccIO should not exceed VccInt by greater than 1.2 V during the power-up sequence.
Applying a logic high state to any I/O pin before VccInt becomes stable is not recommended.
As specified in IEEE 1149.1 (JTAG), the JTMS pin must be held high during reset to avoid entering JTAG
test mode.
VccP must be connected to VccInt through a passive filter circuit. See the RM5200 User’s Manual for
the recommended filter circuit.
