pointer for the line access is initialized to Y address (0). The X address Xi which specifies a
certain line address is one which was stored in the X address register in the previous address
reset or address set cycle. After the reset mode, serial access starts from the address (Xi,0) : line
address is "Xi" and initial bit address on the line is (0).
The Y address counter is reset by this reset mode but the Y address register, which stored the
input initial Y address in the previous address reset cycle or address set cycle, is not reset. The
non-initialized Y address can be used as a preset Y address in the "address jump reset" mode.
4. Line increment reset No.1 - "X address counter increment and Y address counter reset" -
By the "Line increment reset No.1" logic, the X address counter is incremented by one from
the current X address and Y address is reset to address (0). That is, by the reset mode, serial
access from the Y = (0) on the next line is enabled.
5. Line increment reset No.2 - "X address counter increment reset and Y address counter
initialize" -
By the "Line increment reset No.2" logic, the X address counter is incremented by one from
the current X address and Y address is initialized to the Y address set in the previous address
set cycle. This enables block access on the screen.
6. Line hold reset No. 1 (1) operation
When a predetermined input level is set during the reset setting cycle, access is executed
starting from the first word on the current line.
7. Line hold (2) operation
When a predetermined input level is set during the reset setting cycle, access is executed
starting from the word address on the current line which is initialized.
8. Address jump operation
When a predetermined input level is set during the reset setting cycle, a jump may be caused
to the initialized line or word address.
In the case of a read, set the same level in the Y2 and C2 regions for this operation.
Note :During one reset setting cycle, a plurality of resets cannot be set.
