LCD control register L2
Port P2 function and segment pin function of pins P20/SEG16–P23/SEG19 can be switched by setting
register L2.
Set the contents of this register through register A with the TL2A instruction.
Table 2.5.3 shows the LCD control register L2.

Timer control register W3
The timer LC control bit is assigned to the bit 0, and the timer LC count source selection bit is
assigned to the bit 1.
When the LCD display function is used, set the bit 1 to “0.”
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 2.5.4 shows the timer control register W3.
