Boundary scan reset signal input.
Function
Reset signal
The RESET_B signal provides a means of initializing the
µ
PD98413 (i.e. at power on). After the completion of a
µ
reset, the PD98413 can start normal operation. Once
RESET_B has been set to low, it resets the
internal state machines and registers, and forces all 3-
state signals to the high impedance state. Reset input is
performed asynchronously. If low during operation, current
state will be lost.
