N bytes 

N data bytes, size is given  by the Length parameter 

Notes: 

1.  The command identifier 

2. XPRG_MEM_TYPE_APPL 

XPRG_MEM_TYPE_BOOT 
XPRG_MEM_TYPE_EEPROM 
XPRG_MEM_TYPE_FUSE 
XPRG_MEM_TYPE_LOCKBITS 
XPRG_MEM_TYPE_USERSIG 

3. If 

Memory type is XPRG_MEM_TYPE_APPL, XPRG_MEM_TYPE_BOOT or XPRG_MEM_TYPE_EEPROM: 

Bit 0: Write page 

Bit 1: Erase page 

4.  The start address of the data to be written. The address is in the TIF address space 

5.  Can be any value between 1 and 512. If page programming, and the actual page size is bigger than 256, the 

operation must be split into two or more XPRG_WRITE_MEM operations, where only the last operation has the 
Write page bit set. 

Note: Only APP, BOOT and EEPROM handles page operations, for any other memory type, the Length field must 
be set to 1. 

4.  The data to be written. The size is indicated by the Length field.
