READI Module
24.7.6
The READI reset configuration information is received via EVTI and MDI0 to enable or disable the
READI module and select the port size. EVTI and MDI0 are sampled synchronously at the negation of
RSTI. Reset configuration information must be valid on EVTI and MDI0 at least four clocks prior to the
negation of RSTI.
If EVTI is sampled asserted at negation of RSTI, the READI module will be enabled. This is illustrated in
Figure
READI control and status information will be reset and the auxiliary output port will be three-stated, when
RSTI is asserted. System reset will not reset the READI control and status information and not three-state
the auxiliary output port.
Port size configuration is selected via the value of MDI0 at the negation of RSTI.
the READI reset configuration options.
RSTI has a pull-down resistor in the pads. If the auxiliary port is not connected to a tool, READI module
will be in reset state and not drive the auxiliary output port.

EVTI is sampled at the negation of RSTI. Because EVTI is
asserted, the READI module is enabled.
