7. IAP commands
UM10237_4
User manual
Table 642. ISP Return Codes Summary
For in application programming the IAP routine should be called with a word pointer in
register r0 pointing to memory (RAM) containing command code and parameters. Result
of the IAP command is returned in the result table pointed to by register r1. The user can
reuse the command table for result by passing the same pointer in registers r0 and r1. The
parameter table should be big enough to hold all the results in case if number of results
are more than number of parameters. Parameter passing is illustrated in the
Figure
command. The maximum number of parameters is 3, passed to the "Compare" command.
The maximum number of results is 1, returned by all three available IAP commands. The
command handler sends the status code INVALID_COMMAND when an undefined
command is received. The IAP routine resides at 0x7FFF FFF0 location and it is thumb
code.
The IAP function could be called in the following way using C.
Define the IAP location entry point. Since the 0th bit of the IAP location is set there will be
a change to Thumb instruction set when the program counter branches to this address.
#define IAP_LOCATION 0x7ffffff1
Define data structure or pointers to pass IAP command table and result table to the IAP
function:
unsigned long command[5];
unsigned long result[3];
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;
