Figure 13 - Local Port External High Impedance Control Bit Timing (ST-Bus mode)
4.2
Backplane High Impedance Control
The input pin,
BORS
, selects whether the Backplane output streams,
BSTo0-31
are set to high impedance at the
output of the MT90869 itself, or are always driven (active HIGH or active LOW) and a high impedance state, if
required on a per-channel basis, is invoked through an external interface circuit controlled by the
BCSTo0-3
signals. Setting
BORS
to a LOW state will configure the output streams,
BSTo0-31,
to transmit bi-state channel
data with per-channel high-impedance determined by external circuits under the control of the
BCSTo0-3
outputs.
Setting
BORS
to a HIGH state will configure the output streams,
BSTo0-31,
of the MT90869 to invoke a high-
impedance output on a per-channel basis.
The state of the
BORS
pin is detected and the MT90869 configured accordingly during a
RESET
operation, e.g.
following power-up. The BORS pin is an asynchronous input and is expected
to be hard-wired for a particular
system application, although it may be driven under logic control if preferred.
