__RAM_CELL_TEST
Synopsis
Description
Should not be called from user code. This routine is called from a loop within the generated runtime
startup code if the system requires a RAM integrity test before program execution. Upon entry to
this routine, the FSR0 register has been loaded with the RAM cell to test. The value 0x55 will
be assigned to the cell and verified, followed by 0xAA. If either of these values fail verification,
the routine will call ram_test_failed() with an error code in the working register and FSR0 still
containing the address that was in error.
in sequence. If the location being tested contains non volatile data, the value will be backed up in
the PRODL register before the test routine is called and restored upon return from the routine.
insufficient for a particular system’s verification.

This routine is called repeatedly during startup, with each subsequent call testing the next address
This library routine can be overriden by a user’s implementation if the standard cell tests are
void _ram_cell_test(void)
