7.4.1.1 MODULE CONFIGURATION REGISTER (MCR). The MCR controls the serial
module configuration. This register can be either read or written when the module is
enabled and is in the supervisor state. The MCR is not affected by a CPU32 RESET
instruction. Only the MCR can be accessed when the module is disabled (i.e., the STP bit
in the MCR is set).
