Note 1: IREG less than 50 mA, regulator on.
2: After IREG exceeds IREGmax, voltage regulator output will be reduced
until VREG off is reached.

ICSP™ Considerations
The following should be considered when the
MCP2021/2 is connected to pins supporting in-circuit
programming:
• Power used for programming the microcontroller
can be supplied from the programmer, or from the
MCP2021/2.
• The voltage on VREG should not exceed the
maximum output voltage of VREG.
