Bfrom_Crc32Poly; Programming Examples - Analog Devices ADSP-BF506F Hardware Reference Manual

Programming Examples

This is an initcode residing in ROM with the following jobs:
• Register
pCallback
• Call

BFROM_CRC32POLY

This function is unlikely to be called by user code directly. This function
is called as an initcode during the boot process when the CRC calculation
is desired. See
Programming Examples
This section provides programming examples that demonstrate a number
of system reset and booting techniques.
Example System Reset
To perform a system reset, use the code shown in
Listing 24-2.
Listing 24-1. System Reset in Assembly
#include <blackfin.h>
P0.L = LO(BFROM_SYSCONTROL);
P0.H = HI(BFROM_SYSCONTROL);
R0.L = LO(SYSCTRL_SYSRESET);
R0.H = HI(SYSCTRL_SYSRESET);
R1 = 0;
R2 = 0;
CALL (P0);
