Test Mode Condition
In normal application, users should avoid the MTV212M32 entering its test mode or writer mode, outlined as
follow, Adding pull-up resistor to DA8 and DA9 pins is recommended.
Test Mode A: RESET=1 & DA9=1 & DA8=0 & STO=0
Test Mode B: RESET's falling edge & DA9=1 & DA8=0 & STO=1
Writer Mode: RESET=1 & DA9=0 & DA8=1
