There are 16 commons x 40 segments signal drivers in the LCD driver circuit. When a program specifies the
character fonts and line numbers, the corresponding common signals will output drive waveforms and the others
still output unselected waveforms.
It can generate the cursor or blink in the cursor / blink control circuit. The cursor or the blink appears in the digit
at the display data RAM address set in the address counter.
When the address counter is (07)
There are two kinds of data operations - one is 4-bit operations, the other is 8-bit operations. Using 4-bit MPU,
the interfacing 4-bit datas are transferred by 4-busline (DB7 - 4). DB3 - 0 buslines are not used. Using 4-bit
MPU to interface 8-bit datas needs two times. First, the higher order 4-bit datas are transferred by 4-busline
(DB7 - 4). Secondly, the lower order 4-bit datas are transferred by 4-busline (DB3 - 0). Using 8-bit MPU, the
interfacing 8-bit datas are transferred by 8-buslines (DB7 - 0).
