Connection for user-supplied backup battery
up to 39 parallel digital I/0 lines configurable with four layers
of alternate functions
Can be configured for 8 data lines and
6 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
•
1 asynchronous clocked serial port shared with program-
ming port
•
1 clocked serial port shared with serial flash
Maximum asynchronous baud rate = CLK/8
Slave port allows the RCM5400W to be used as an intelligent
peripheral device slaved to a master processor
Ten 8-bit timers (6 cascadable from the first),
one 10-bit timer with 2 match registers, and
one 16-bit timer with 4 outputs and 8 set/reset registers
4 channels synchronized PWM with 10-bit counter
4 channels variable-phase or synchronized PWM with 16-bit
counter
2-channel input capture can be used to time input signals from
2-channel quadrature decoder accepts inputs
from external incremental encoder modules
