Signal Summary
MPIO32B3 / VFLS0 / MSEO
2
I/O
MPIO32B3
unless the
Nexus (READI)
port is enabled.
MIOS14 GPIO 3. Allows the signal to be used as a
general-purpose input/output.
O
Visible History Buffer Flush Status 0. This signal is output by
the MPC561/MPC563 to allow program instruction flow
tracking. It reports the number of instructions flushed from
O
MSEO. Message start/end out (MSEO) is an output signal
which indicates when a message on the MDO signals has
started, when a variable length packet has ended, and when
the message has ended. External latching of MSEO occurs
on rising edge of MCKO.
MPIO32B4 / VFLS1
1
I/O
MPIO32B4
MIOS14 GPIO 4. Allows the signal to be used as a
general-purpose input/output.
O
Visible History Buffer Flush Status 1. This signal is output by
the MPC561/MPC563 to allow program instruction flow
tracking. It reports the number of instructions flushed from
MPIO32B5 / MDO5
1
I/O
MPIO32B5
unless the
Nexus (READI)
port is enabled,
then MDO5.
MIOS14 GPIO 5. Allows the signal to be used as a
general-purpose input/output.
O
READI Message Data Out. Message data out (MDO5) is an
output signal used for uploading OTM, BTM, DTM, and
read/write accesses. External latching of MDO occurs on
rising edge of MCKO. Eight MDO signals are implemented.
MPIO32B6 / MPWM4 /
MDO6
1
I/O
MPIO32B6
unless the
Nexus (READI)
port is enabled,
then MDO6.
MIOS14 GPIO 6. Allows the signal to be used as
general-purpose input/output.
I/O
Pulse Width Modulation 4. These signals provide variable
pulse width outputs at a wide range of frequencies.
O
READI Message Data Out. Message data out (MDO6) is an
output signal used for uploading OTM, BTM, DTM, and
read/write accesses. External latching of MDO occurs on
rising edge of MCKO. Eight MDO signals are implemented.
MPIO32B[7:9] /
MPWM[5, 20:21]
3
I/O
MPIO32B[7:9]
MIOS14 GPIO[7:9]. Allows these signals to be used as
general-purpose input/outputs.
I/O
Pulse Width Modulation [5, 20:21]. These signals provide
variable pulse width outputs at a wide range of frequencies.
MPIO32B10 / PPM_TSYNC
1
I/O
MPIO32B10
MIOS14 GPIO 10. This function allows the signals to be
used as general-purpose inputs/outputs.
O
PPM_TSYNC. Synchronizes the data between the PPM and
peripheral devices.
MPIO32B11 / C_CNRX0 6
1
I/O
MPIO32B11
MIOS14 GPIO 11. This function allows the signals to be
used as general-purpose inputs/outputs.
I
TouCAN_C Receive Data. This is the serial data input signal
for the TouCAN_C module.
