(to support RTC)
up to 35 parallel digital I/0 lines configurable with four layers of alternate
functions
Can be configured for 8 data lines and
8 address lines (shared with parallel I/O lines),
6 high-speed, CMOS-compatible ports:
•
all 6 configurable as asynchronous (with IrDA), 4 as clocked serial (SPI),
and 2 as SDLC/HDLC
•
