Reflects whether the current hashing block is the final block in the hashing operation, so the hash padding
should be applied by hardware.
Reflects whether the current hashing block is the initial block in the hashing operation, so the hash registers
should be initialized before the operation.
When set, indicates the payload contains the key. This bit takes precedence over the OTP_KEY control
Reflects whether a hardware-based key should be used. The KEY_SELECT field from the Control1 field is
used to select from multiple hardware keys. The PAYLOAD_KEY bit takes precedence over the OTP_KEY
bit.
Reflects whether the cipher block should load the initialization vector from the payload for this operation.
When the cipher block is enabled, this bit indicates whether the operation is encryption or decryption.
0x01
0x00
Reflects whether the DCP should perform a blit operation. Source data is always continuous and the
destination buffer is written in run/stride format. When set, the
BUFFER_SIZE field is treated as two 16-bit values for the X-Y extents of the blit operation.
Reflects whether the selected hashing function should be enabled for this operation.
Reflects whether the selected cipher function should be enabled for this operation.
Reflects whether the selected hashing function should be enabled for this operation.
Reflects whether the next packet's address is located following this packet's payload.
Reflects whether the next command pointer register should be loaded into the channel's current descriptor
pointer.
Reflects whether the channel's semaphore should be decremented at the end of the current operation. When
the semaphore reaches a value
of zero, no more operations will be issued from the channel.
Reflects whether the channel should issue an interrupt upon completion of the packet.
