PLIC Registers
13.5.8 Loopback Control Register (PLCR)
All bits in this register are cleared on hardware or software reset.
The PLCR is an 8-bit register containing the configuration information for all four ports on
the MCF5272.

GCI Activation.
0 Default reset value.
1 Causes Dout to transition to a logic low for the respective port. This bit is only operational when
the port is in GCI mode. Setting the ACT bit in any other mode has no effect. It is the responsibility
of the CPU to clear the ACT bit when normal operation on Dout is required. This bit is intended to
be used to request activation from the upstream DCL/FSC driver. Periodic interrupts commence as
soon as the upstream device generates DCL, provided the appropriate interrupts, such as IE,
B1RIE, and so on, are enabled for the port.
Data multiplex.
0 port 3 Dout and Din are multiplexed onto Dout1 and Din1.
1 enables port 3 Dout and Din to be connected to dedicated output and input pins, DOUT3 and
B2 channel shift direction.
