USER’S MANUAL
The following programming examples involve using the system integration module
(SIM). The programs include:
Refer to
SIM.
Description : This program demonstrates a simple I/O usage of
• Using ports E and F.
• Setting up U1 and U3 RAM slots with two 32K X 8 RAM chips using chip selects.
• Demonstrating the ability of the M68HC16 to change clock frequencies on the fly.
• Demonstrating the software watchdog, the periodic interrupt, and an autovector.

Ports E and F with a loop that will load Port E
with a number, pass that number over to
Port F through a hardwire of the M68HC16Z1EVB, and then
read
that number from the Port F data register.
Port E will be incremented each loop.
The hardwire of the M68HC16Z1EVB is from DSACK0 to MODCLK,
from DSACK1 to IRQ1, and from AVEC to IRQ2.
The numbers start at #$00 and go to #$07.
