13.2.1
The LCD port control register is an 8-bit read/write register, used for selecting the duty cycle and
the LCD driver and pin functions, etc. Upon reset, LPCR is initialized to H'00.
Bits 7 to 5—Duty and Common Function Select (DTS1, DTS0, CMX): Bits 7 to 6 select a
driver duty of static, 1/2, 1/3, or 1/4. Bit 5 determines whether the common pins not used at a
given duty are to be used as ports or, in order to increase the common driving capacity, as multiple
pins outputting the same waveform.
