Chapter 3 Port Integration Module (PIM9E256V1)
3.3.4
Port Q is associated with the Pulse Width Modulator (PMF) modules. Each pin is assigned according to
the following priority: PMF > general-purpose I/O.
When a current status or fault function is enabled, the corresponding pin becomes an input. PQ[3:0] are
connected to FAULT[3:0] inputs and PQ[6:4] are connected to IS[2:0] inputs of the PMF module. Refer
to
enabling and disabling these PMF functions.
During reset, port Q pins are configured as high-impedance inputs.
3.3.4.1
Read: Anytime. Write: Anytime.
If the associated data direction bit (DDRQx) is set to 1 (output), a read returns the value of the I/O register
bit. If the associated data direction bit (DDRQx) is set to 0 (input), a read returns the value of the pin.
3.3.4.2
Read: Anytime. Write: Never, writes to this register have no effect.
This register always reads back the status of the associated pins.
