REGISTER 2-15: MACCON1 (MAC CONTROL 1 REGISTER) (CONTINUED)
ADDRESS: 0x10
bit 0
SECFLAGOVR: Security Flag Override bit
The user can override security flags used in the CCM-CTR, CBC-MAC and CCM operation, otherwise
the device uses the standard (2003/2006) definition.

Zero-length address occurs when the corresponding DAddrPrsnt/SAddrPrsnt bits of the packet Frame Con-
trol field are set to ‘0’.
Use ADDRSZ field while receiving and transmitting, and must not be modified while RXEN or TXST is set.
Use FRMFMT field while receiving and transmitting, and must not be modified while RXEN or TXST is set.
In Debug mode, use this register bit to determine the frame format for both TX/RX frame in the packet
buffers.
