<p>Interrupts and flags management functions. </p>
|
|
<pre class="fragment"> ===============================================================================
|
|
##### Interrupts and flags management functions #####
|
|
===============================================================================
|
|
|
|
[..] This section provides functions allowing to configure the HASH Interrupts and
|
|
to get the status and clear flags and Interrupts pending bits.
|
|
|
|
[..] The HASH provides 2 Interrupts sources and 5 Flags:
|
|
|
|
*** Flags : ***
|
|
===============
|
|
[..]
|
|
(#) HASH_FLAG_DINIS : set when 16 locations are free in the Data IN FIFO
|
|
which means that a new block (512 bit) can be entered into the input buffer.
|
|
|
|
(#) HASH_FLAG_DCIS : set when Digest calculation is complete
|
|
|
|
(#) HASH_FLAG_DMAS : set when HASH's DMA interface is enabled (DMAE=1) or
|
|
a transfer is ongoing. This Flag is cleared only by hardware.
|
|
|
|
(#) HASH_FLAG_BUSY : set when The hash core is processing a block of data
|
|
This Flag is cleared only by hardware.
|
|
|
|
(#) HASH_FLAG_DINNE : set when Data IN FIFO is not empty which means that
|
|
the Data IN FIFO contains at least one word of data. This Flag is cleared
|
|
only by hardware.
|
|
|
|
*** Interrupts : ***
|
|
====================
|
|
[..]
|
|
(#) HASH_IT_DINI : if enabled, this interrupt source is pending when 16
|
|
locations are free in the Data IN FIFO which means that a new block (512 bit)
|
|
can be entered into the input buffer. This interrupt source is cleared using
|
|
HASH_ClearITPendingBit(HASH_IT_DINI) function.
|
|
|
|
(#) HASH_IT_DCI : if enabled, this interrupt source is pending when Digest
|
|
calculation is complete. This interrupt source is cleared using
|
|
HASH_ClearITPendingBit(HASH_IT_DCI) function.
|
|
|
|
*** Managing the HASH controller events : ***
|
|
=============================================
|
|
[..] The user should identify which mode will be used in his application to manage
|
|
the HASH controller events: Polling mode or Interrupt mode.
|
|
|
|
(#) In the Polling Mode it is advised to use the following functions:
|
|
(++) HASH_GetFlagStatus() : to check if flags events occur.
|
|
(++) HASH_ClearFlag() : to clear the flags events.
|
|
|
|
(#) In the Interrupt Mode it is advised to use the following functions:
|
|
(++) HASH_ITConfig() : to enable or disable the interrupt source.
|
|
(++) HASH_GetITStatus() : to check if Interrupt occurs.
|
|
(++) HASH_ClearITPendingBit() : to clear the Interrupt pending Bit
|
|
(corresponding Flag). </pre> <h2 class="groupheader">Function Documentation</h2>
