On these devices, COM3 and SEG15 are shared on one pin, limiting the device from driving 64 pixels.
LCDEN: LCD Driver Enable bit
1 = LCD driver module is enabled
0 = LCD driver module is disabled
SLPEN: LCD Driver Enable in Sleep Mode bit
1 = LCD driver module is disabled in Sleep mode
0 = LCD driver module is enabled in Sleep mode
WERR: LCD Write Failed Error bit
1 = LCDDATAn register written while the WA bit of the LCDPS register = 0 (must be cleared in
0 = No LCD write error
