External Signal Description
Each unified channel has one input and one output signal connected to the channel’s I/O pin. Refer to the
SIU, eTPU, and DSPI sections for details about the connection to pads and other modules.
The internal
output disable input
) are provided to implement the output
disable feature needed for motor control. They are connected to EMIOS_Flag_Out signals according to
Section 16.2.1.1, “Output Disable Input—eMIOS Output Disable Input Signals
16.2.1
External Signals
When configured as an input, EMIOS
n
is synchronized and filtered by the programmable input filter (PIF).
The output of the PIF is then used by the channel logic and is available to be read by the MCU through the
UCIN bit of the EMIOS_CSR
n
.
When configured as an output, EMIOS
n
is a registered output and is available for reading by the MCU
through the UCOUT bit of the EMIOS_CSR
n
.

A value of 0 refers to the reset value of the signal. Hi-Z refers to the state of the external pin if a tri-state
output buffer is controlled by the corresponding eMIOS signal.
