6.5 SERIAL MODULE INITIALIZATION SEQUENCE
If the serial capability of the MC68306 is being used, the following steps are required to
properly initialize the serial module.
Command Register (DUCR)
The following steps program both channels:
Interrupt Vector Register (DUIVR)
Interrupt Mask Register (DUIMR)
Auxiliary Control Register (DUACR)
Output Port Control Register (DUOPCR)
The following steps are channel specific:
Clock Select Register (DUCSR)
Mode Register 1 (DUMR1)
Mode Register 2 (DUMR2)
MOTOROLA
• Reset the receiver and transmitter for each channel.
• Program the vector number for a serial module interrupt.
• Enable the desired interrupt sources.
• Select baud rate set (BRG bit).
• Initialize the input enable control (IEC bits).
• Select counter/timer mode and clock source if necessary.
• Select the function of the output port pins.
• Select the receiver and transmitter clock.
• If desired, program operation of receiver ready-to-send (RxRTS bit).
• Select receiver-ready or FIFO-full notification (R/F bit).
• Select character or block error mode (ERR bit).
• Select parity mode and type (PM and PT bits).
• Select number of bits per character (B/Cx bits).
• Select the mode of channel operation (CMx bits).
• If desired, program operation of transmitter ready-to-send (TxRTS bit).
The serial module registers can be accessed by word or byte
operations, but only the data byte D7–D0 is valid.
