Block Diagram
• Port C can bitting select I/O. The input after resets.
• Port D can select I/O only by (PD0-3, PD4-7) every four bits. The input after resets.
• PF4-7 of port F can bitting select I/O. The input after resets.
• Port I can bitting select I/O. The input after resets.
• Port J can bitting select I/O. The input after resets.
• PE6 Attention concerning PE7. Adjust to 0.7V or more both PE6 and PE7 when RST standing up from L to H.
Please note entering in the test mode of the microcomputer. Pull-up is necessary.
• When resetting : Makes to Hi-Z excluding PE6 and PE7. PE6 and PE7 are made H level.
• Connect the 90th terminals NC with Vdd.
• Connect both of the terminal Vss of the 41th pin and the 88th pin with GND.
• It is terminal OPEN and OK for the model without RDS.
RDSDATA is set to make to the output mode and to output LOW with the microcomputer.
• The processing such as pull-down is necessary for RDSCLK for the model without RDS.
