Conservation of the Register
Information
The T5743 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 generated if the supply voltage V
S
drops below the threshold voltage V
ThReset
. The default parameters are programmed into
the configuration registers in that condition. Once V
S
exceeds V
ThReset
the POR is can-
celled after the minimum reset period t
Rst
. A POR is also generated 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 represented by the fixed frequency f
RM
at a 50% duty-cycle. RM can be
cancelled via a Low pulse t1 at Pin DATA.
