Nothing is assigned. This bit is a write disable bit.
When this bit is read out, the value is “0.”
Notes 1: When bit 5 =“0” and bit 4 = “1,” there is output same as a character or
border output from pin OUT1.
Do not set bit 5 = “0” and bit 4 = “0.”
2: When only bit 7 =“1” and bit 5 “0,” there is output from pin OUT2.
