Description
When set, converts SEGDIO3 and SEGDIO2 to interface with external EEPROM.
SEGDIO2 becomes SDCK and SEGDIO3 becomes bi-directional SDATA, but only if
LCD_MAP[2] and LCD_MAP[3] are cleared.
Causes VPULSE to be output on SEGDIO1, if LCD_MAP[1]=0.
Causes WPULSE to be output on SEGDIO0, if LCD_MAP[0]=0.
Causes XPULSE to be output on SEGDIO6 , if LCD_MAP[6]=0.
Causes YPULSE to be output on SEGDIO7 , if LCD_MAP[7]=0.
Serial EEPROM interface data.
Serial EEPROM interface control.
Specifies the power equation.
