User manual
unsigned long result[4];
or
unsigned long * command;
unsigned long * result;
command=(unsigned long *) 0x……
result= (unsigned long *) 0x……
Define pointer to function type, which takes two parameters and returns void. Note the IAP
returns the result with the base address of the table residing in R1.
typedef void (*IAP)(unsigned int [],unsigned int[]);
IAP iap_entry;
Setting function pointer:
iap_entry=(IAP) IAP_LOCATION;
Whenever you wish to call IAP you could use the following statement.
iap_entry (command, result);
As per the ARM specification (The ARM Thumb Procedure Call Standard SWS ESPC
0002 A-05) up to 4 parameters can be passed in the r0, r1, r2 and r3 registers
respectively. Additional parameters are passed on the stack. Up to 4 parameters can be
returned in the r0, r1, r2 and r3 registers respectively. Additional parameters are returned
indirectly via memory. Some of the IAP calls require more than 4 parameters. If the ARM
suggested scheme is used for the parameter passing/returning then it might create
problems due to difference in the C compiler implementation from different vendors. The
suggested parameter passing scheme reduces such risk.
The flash memory is not accessible during a write or erase operation. IAP commands,
which results in a flash write/erase operation, use 32 bytes of space in the top portion of
the on-chip RAM for execution. The user program should not be use this space if IAP flash
programming is permitted in the application.
