Description
Source A. The Source field is a 32-bit pointer to system memory. It points to the start of
data to be encrypted or decrypted. The lower four bits must be written as zero and
always read zero. This forces the data fetching to begin on a 16-byte boundary. This
register should not be changed during an AES encryption or decryption operation using
the A pointer (i.e., while STA is asserted, SB Memory Offset 000h[0] = 1). This register
can be modified during an operation using the B pointer set (while STB is asserted, SB
Memory Offset 004h[0] = 1).
Reserved. Set to 0.
Description
Reserved.
AES Interrupt Status.
0: INT not pending.
1: INT pending.
Writing a 1 to this bit clears the status.
18: EEPROM operation complete.
17: AES context B complete.
16: AES context A complete.
Reserved.
AES Interrupt Mask.
0: Enable, unmask the INT.
1: Disabled, mask the INT.
2: When enabled (0), allows EEPROM operation complete INT.
1: When enabled (0), allows AES context B complete INT.
0: When enabled (0), allows AES context A complete INT.
