• BFCOM: Burst Flash Controller Operating Mode
• BFCC: Burst Flash Controller Clock
• AVL: Address Valid Latency
The Address Valid Latency is defined as the number of BFC Clock Cycles from the first BFCK rising edge when BFAVD is
asserted to the BFCK rising edge that samples read data. The Latency is equal to AVL + 1.
