Recommended Operating Conditions
Notes
1.
2.
3.
VccIO
should not exceed
VccInt
by greater than 2.0 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.
VssP
must be connected to
Vss
through a passive filter circuit. See the RM5200 User’s Manual for the recommended filter circuit.
