Conservation of the Register Information
The T5743N implies an integrated power-on reset and
brown-out detection circuitry to provide a mechanism to
preserve the RAM register information.
According to figure 32, a power–on reset (POR) is gener-
ated if the supply voltage V
voltage V
grammed into the configuration registers in that
condition. Once V
after the minimum reset period t
ated when the supply voltage of the receiver is turned on.
To indicate that condition, the receiver displays a reset
marker (RM) at Pin DATA after a reset. The RM is repre-
