10.3 Interfacing to the MPU The IC can send data in either two 4-bit operations, thus allowing interfacing with 4-bit or 8-bit MPUs.

For 4-bit interface data, only four bus lines (DB4 to DB7) are used for transfer. Bus lines DB0 to FB3 are disabled. The data transfer betweenthe IC and the MPU is completed after the 4-bit data has been transferredtwice. As for the order of data transfer, the four high order bits (for 8-bit operation, DB4 to DB7) are transferred before the four low order bits (for8-bit operation, DB0 to DB3)The busy flag must be checked (one instruction) after the 4- bit data hasbeen transferred twice. After two 4-bit operations then transfer the busyflag and address counter data.

Notes : 1. Character code bits 0 to 2 correspond to CGRAM address bits 3 to 5 (3 bits: 8 type). 2. CGRAM address bits 0 to 2 designate the character pattern line position. The 8th line is the

cursor position and its display is formed by a logical OR with the cursor. Maintain the 8th line data, corresponding to the cursor display position, at 0 as the cursor display. If the 8th line data is 1, 1bit will light up the 8th line regardless of the cursor presence.3. Character pattern row positions correspond to CGRAM data bits 0 to 4 (bit 4 being at the left).4. As shown Table 5, CGRAM character patterns are selected when character code bits 4 to 7 are all 0. However, since character code bit 3 has no effect, the R display example above can be selected by either character code 00H or 08H.5. 1 for CGRAM data corresponds to display selection and 0 to non-selection. Indicates no effect.
