MRF24XA
REGISTER 2-16: MACCON2 (MAC CONTROL 2 REGISTER)
R/W-0000
CHANNEL<3:0>
bit 7
ADDRESS: 0x11
R/W/HS-0000
SECSUITE<3:0>
bit 0
Legend: R = Readable bit W = Writable bit
-n = Value at POR
‘1’ = Bit is set
r = Reserved
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-4
bit 3-0
CHANNEL<3:0>: TX/RX operating channel bits
These register bits are used as the current operating channel for TX/RX operation⁽¹⁾.
0x0 = Channel 11
0x1 = Channel 12

0xF = Channel 26
SECSUITE<3:0>: Security suite bits⁽²⁾
1111 = AES-CBC-MAC-32 (Authentication with a 32-bit MAC, but no Encryption/Decryption)
1110 = AES-CBC-MAC-64 (Authentication with a 64-bit MAC, but no Encryption/Decryption)
1101 = AES-CBC-MAC-128 (Authentication with a 128-bit MAC, but no Encryption/Decryption)
1100 = Reserved
1011 = Reserved
1010 = Reserved
1001 = AES-CTR (Encryption/Decryption, but no Authentication)
1000 = AES-ECB (Encryption only)
0111 = AES-ENC-MIC-128 (Authentication with a 128-bit MAC and Encryption/Decryption)
0110 = AES-ENC-MIC-64 (Authentication with a 64-bit MAC and Encryption/Decryption)
0101 = AES-ENC-MIC-32 (Authentication with a 32-bit MAC and Encryption/Decryption)
0100 = AES-ENC (Encryption/Decryption, but no Authentication)
0011 = AES-MIC-128 (Authentication with a 128-bit MAC, but no Encryption/Decryption)
0010 = AES-MIC-64 (Authentication with a 64-bit MAC, but no Encryption/Decryption)
0001 = AES-MIC-32 (Authentication with a 32-bit MAC, but no Encryption/Decryption)
0000 = No security services enabled, or security is handled by upper protocol layers; ignore the setting
of the SecEn bit (if value is ‘0’)
Note 1: Use this field while receiving and transmitting, and must not be modified while RXEN or TXST is set.
2: In 15.4-2006 Standard mode MAC layer security processing, the Register field is automatically set based
on the SecLvl bits of the AuxSecHdr Control field.
