TCS3–TCS0—Transmitter Clock Select

These bits select the baud rate clock for the channel transmitter from a set of baud rates

listed in Table 7-5. The baud rate set selected depends upon ACR bit 7. Set 1 is

selected if ACR bit 7 = 0, and set 2 is selected if ACR bit 7 = 1. The transmitter clock is

always 16 times the baud rate shown in this list, except when SCLK is used.

7.4.1.7 COMMAND REGISTER (CR). The CR is used to supply commands to the

channel. Multiple commands can be specified in a single write to the CR if the commands

are not conflicting—e.g., reset transmitter and enable transmitter commands cannot be

specified in a single command. This register can only be written when the serial module is

enabled (i.e., the STP bit in the MCR is cleared).
