Opcode
The opcodes are listed in Table 7-1.
INIT TX and RX PARAMETERS. This command initializes the transmit and receive pa-
rameters in the parameter RAM to the values that they had after the last reset of the CP.
This command is especially useful when switching protocols on a given serial channel.
INIT RX PARAMETERS. This command initializes the receive parameters of the serial
channel.
INIT TX PARAMETERS. This command initializes the transmit parameters of the serial
channel.
ENTER HUNT MODE. This command causes the receiver to stop receiving and begin
looking for a new frame. The exact operation of this command may vary depending on the
protocol used.
STOP TX. This command aborts the transmission from this channel as soon as the trans-
mit FIFO has been emptied. It should be used in cases where transmission needs to be
stopped as quickly as possible. Transmission will proceed when the RESTART command
is issued.
