13.5.13 GCI Monitor Channel Transmit Registers (P0GMT–P3GMT)
All bits in these registers are read/write and are cleared on hardware or software reset.
The PnGMT registers are 16 bit register containing the control and monitor channel bits to be transmitted
for each of the four ports on the MCF5272.
A byte of monitor channel data to be transmitted on a certain port is put into an associated register using
the format shown in
successfully transmitted.

E bit. Both PnGMT[L] and PnGMT[R] must be set for the monitor channel controller to send the end of
message signal. PnGMT[M7:0] are ignored and 0xFF is sent with the end of message condition
necessitating sending the monitor channel information using PnGMT[R] to control the monitor channel
transmitter, followed at the end of the frame by setting PnGMT[L] and PnGMT[R]. The L bit is automatically
cleared by the GCI controller.
Automatically cleared by the GCI controller when it generates a transmit acknowledge (ACK bit in PGMTS
register) or when the L bit is reset.
