Abstract
PURPOSE: To obtain a display unit capable of displaying more characters by using memory buffers with the same capacity.
CONSTITUTION: When bit (n) set to register 3 is "1", register 3 makes memory address counter 1 count up by one, a character code is read out from the next address (A+1), and the character code part is set, n/2 bit by n/2 bit, to buffers 10' and 11'. Buffers 10 and 11 are changed over to buffers 10' and 11' by register 3 and bit (n) of the character code is set to register 3. At this point of time, a total of 3/2n bits of buffers 10, 11 and 10' are selected by selector 4, added newly and sent as character code (3/2n bits) to character generating circuit 7. When bit (n) of the character code read out from address (A+1) and set to register 3 is "1", on the other hand, 3/2n bits are similarly sent from address (A+2) of memory buffer 2 to circuit 7. 2: memory buffer 1: memory address counter
