R/W :
A register to switch the servo port/general-purpose port, and the CFG input system.
SPMR is an 8-bit read/write register. Bit 6 is reserved; writing in it is invalid. If read is
attempted, an undetermined value is read out. It is initialized to H'40 by a reset or stand-by.
Bit 7: CTLSTOP Bit (CTLSTOP)
Controls whether the CTL circuits are operated or stopped.
