(I-14) PC-98
This bit switches the PC-98 (400-vertical line) display mode. Operation shifts to PC-98 mode when PC-98 is
Low. However, since this function supports the LCX012BL, PC-98 is normally (modes other than LCX012BL/
PC-98 mode) set High.
This function is used to display PC-98 (640
×
400) images in the display area of the LCX012BL (644
×
484).
The upper and lower 42 lines outside of the display area are black display during this mode.
The vertical high-speed scanning and precharge black writing methods have been introduced as methods for
writing these black areas. VCK is shifted to double-speed operation to realize vertical double-speed transfer
and enable black display within the limited V blanking. Also, the black level during this period is determined by
the PSIG (LCX012BL) level and written at the PCG (LCX012BL pin) timing.
At this time, HST is masked, limiting the video signal input.
