The
μ
PD161401 can set the main duty cycles in a range of 1/80, 1/72 and 1/64 duty, the sub-duty cycles in a range of
1/48, 1/40, 1/32, 1/24 and 1/16 duty. This can be done by setting MDT6 to MDT0 and SDT6 to SDT0 of the main duty
setting register (R14) and sub-duty setting register (R17) as

Setting of LCD N-line inversion and M-line shift
During main duty display, the shift amount of the reverse position of AC driving and the reverse position of each
display frame can be set by the main duty N-line inversion register (R15) and main duty M-line shift register (R16). They
can also be set by the sub-duty N-line inversion register (R18) and sub-duty M-line shift register (R19) during sub-duty
display.
The N-line reverse cycle function can set a line to be reversed as shown in
Table 5
27
, depending on the setting of
MID5 to MID0 or SID5 to SID0 of the main or sub-duty N-line inversion register.
The M-line shift amount of the reverse position of each display frame can be set as shown in
Table 5
28
, by using
MSD5 to MSD0 or SSD5 to SSD0 of the main or sub-duty M-line shift register.
