memset

void memset (
  unsigned long start_address, /* memory start address */
  unsigned long length,        /* memory length        */
  unsigned char value          /* value to write       */
)

The debug function memset fills the memory specified through start address and length with the character value.

Note

• The order of the parameters length and value of the debug function memset are inverted compared to the standard C function memset.
• [MDK] The parameter length can specify a maximum amount of memory of 64 KB.
• [PK51, DK251] The parameter length can specify a maximum amount of memory of 64 KB.
• [C166] The parameter length can specify a maximum amount of memory of 16 MB.
