9.1.6 Security Operation Status
9.1.7 SRAM Register Summary
9.1.8 Register Description
8168C-MCU Wireless-02/10
The status of the security processing is indicated by register 0x82 (AES_STATUS).
After 24 µs AES processing time register bit AES_DONE changes to 1 (register 0x82,
AES_STATUS) indicating that the security operation has finished, see parameter
10.4.14 in section 10.4.
The following registers are required to control the security module:
Table 9-2. SRAM Security Module Address Space Overview
These registers are only accessible using SRAM write and read; for details, refer to
section 4.3.3. Note that the SRAM registers are reset when entering the SLEEP state.
Register 0x82 (AES_STATUS):
This read-only register signals the status of the security module and operation.
Table 9-3. Register 0x82 (AES_STATUS)
• Bit 7 – AES_ER
This SRAM register bit indicates an error of the AES module. An error may occur for
instance after an access to SRAM register 0x83 (AES_CTRL) while an AES operation
is running or after reading less than 128 bits from SRAM register space 0x84 – 0x93
(AES_STATE).
