Timer control register W3
The timer LC control bit is assigned to the bit 0, and timer LC count source selection bit is assigned
to the bit 1.
Set the contents of this register through register A with the TW3A instruction. The TAW3 instruction
can be used to transfer the contents of register W3 to register A.
Table 2.3.4 shows the timer control register W3.
