Description
Message Clockout (MCKO) is a free-running output clock to
development tools for timing of MDO and MSEO pin functions.
Message Data Out (MDO[5:0]) are output pins used for all messages
generated by the device. In single datarate mode, external latching of
MDO shall occur on rising edge of MCKO. In double datarate mode,
external latching of MDO shall occur on both edges of MCKO.
Message Start/End Out (MSEO[1:0]) pins indicate when a message
on the MDO pins has started, when a variable length packet has
ended, and when the message has ended. In single datarate mode,
external latching of MSEO shall occur on rising edge of MCKO. In
double datarate mode, external latching of MSEO shall occur on both
edges of MCKO.
Event Out (EVTO) is an output pin which can be configured to toggle
every time a message is inserted into the Transmit Queue, when the
CPU entered OCD Mode, or when a breakpoint or watchpoint hit
occured, as configured by the EOS bits in the Development Control
register .
Event In (EVTI) is an input which, when a high-to-low transition occurs,
a processor is halted (breakpoint) or program and data
synchronization messages are transmitted from the OCD controller, as
configured by the EIC bits in the Development Control register.
