3.2.2 Real-Time Clock
If you plan to use the real-time clock functionality in your application, you will need to set
the real-time clock. Use the
SAMPLES\RTCLOCK
program in the Dynamic C
how to read and set the real-time clock.
3.2.3 Use of Serial Flash (Dynamic C v. 10.54 and later)
The following sample programs from the SAMPLES\RCM4400W\Serial_Flash folder may
be used with the RCM4400W as long as you are using Dynamic C v. 10.54 or later.

from a browser at http://10.10.6.100/. You will likely have to first “configure” your net-
work interface card for a “10Base-T Half-Duplex,” “100Base-T Half-Duplex,” or an

serial flash chip. When the sample program starts running, it attempts to initialize a
serial flash chip on Serial Port B. Once a serial flash chip is found, the user can perform
five different commands to print out the contents of a specified page, set all bytes on
the specified page to a single random value, clear (set to zero) all the bytes in a speci-
fied page, set all bytes on the specified page to a given value, or save user-specified text
to a selected page.
NOTE: This sample program accesses the serial flash directly and may overwrite other
data stored in the ustomer-accessible 800KB area, including the FAT file system. Do
not run this sample program if you have any important data on the serial flash device.
