17.4.4
In the H8S/2268 and 2264, the LCD controller/driver can be operated even in the power-down
modes. The operating state of the LCD controller/driver in the power-down modes is summarized
in table 17.7.
In subactive mode, watch mode, and subsleep mode, the system clock oscillator stops, and
therefore, unless φ
be supplied and display will halt. Since there is a possibility that a direct current will be applied to
the LCD panel in this case, it is essential to ensure that φ
In the software standby mode the segment output and common output pins switch to I/O port
status. In this case if a port’s DDR or PCR bit is set to 1, a DC voltage could be applied to the
LCD panel. Therefore, DDR and PCR must never be set to 1 for ports being used for segment
output or common output.
