Implementation of the cc2538 AES/SHA cryptoprocessor driver. | |
file | crypto.h |
Header file for the cc2538 AES/SHA cryptoprocessor driver. | |
Functions | |
void | crypto_isr (void) |
The AES/SHA cryptoprocessor ISR. | |
Crypto functions | |
void | crypto_init (void) |
Enables and resets the AES/SHA cryptoprocessor. | |
void | crypto_enable (void) |
Enables the AES/SHA cryptoprocessor. | |
void | crypto_disable (void) |
Disables the AES/SHA cryptoprocessor. | |
void | crypto_register_process_notification (struct process *p) |

void crypto_isr | ( | void | ) |
The AES/SHA cryptoprocessor ISR.
This is the interrupt service routine for the AES/SHA cryptoprocessor. This ISR is called at worst from PM0, so lpm_exit() does not need to be called.
Definition at line 59 of file crypto.c.
References AES_IRQn, and process_poll().
void crypto_register_process_notification | ( | struct process * | p | ) |
Registers a process to be notified of the completion of a crypto operation.
p | Process to be polled upon IRQ |
