The ATA5743 has integrated power-on reset and brown-out detection circuitry to provide a
mechanism to preserve the RAM register information.
As seen in
drops below the threshold voltage V
configuration registers in that condition. Once V
minimum reset period t
turned on.
To indicate that condition, the receiver displays a reset marker (RM) at pin DATA after a reset.
The RM is represented by the fixed frequency f
a Low pulse t1 at pin DATA.
