Zilog Developer Studio II – Z8 Encore!
User Manual
Example
#include

char x;

void main()

{

INIT_FLASH(_DEFFREQ); /* Target clock frequency */

WRITE_FLASH((rom const *)0x2f00,x); /* write to Flash */

x = READ_FLASH((rom const *)0x2f00); /* read from Flash */

}
Beginning with the ZDS II for Z8 Encore! release 4.8, there is a slight change in the func-
tion prototype for READ_FLASH.
Previous Prototype
#if defined(_Z8F642)

char reentrant READ_FLASH(rom const void *addr);

#else

char intrinsic reentrant READ_FLASH(rom const void *addr);

#endif
New Prototype
char reentrant READ_FLASH(rom const void *addr);
For most Z8 Encore! processor variants, the intrinsic keyword has been deleted in the
ZDS II release 4.8.0. This change is taken care of automatically as long as you are using
the standard Zilog library version of READ_FLASH and including the standard header
file
ez8.h . However, since the new standard header uses the new prototype, if you have
customized READ_FLASH in your application, you must make modifications so that the
header and function declarations agree.
READ_NVDS
The READ_NVDS function is a Zilog function that reads a value from NVDS memory at
the specified address.
Synopsis
#include

reentrant char READ_NVDS(char address)

reentrant char nvds_read(char address)
Returns
The function returns the character read from NVDS at the address specified.
