–

Latched MCU address output

–

Special function I/Os.

–

I/O ports may be configured as open-drain

outputs.

■

IN-SYSTEM PROGRAMMING (ISP) WITH

JTAG

–

Built-in JTAG compliant serial port allows

full-chip In-System Programmability

–

Efficient manufacturing allow easy

product testing and programming

–

Use low cost FlashLINK cable with PC

■

PAGE REGISTER
