111 / 387 page  1-93 REJ09B0212-0100Z Rev.1.00 Jan 14, 2005 3804 Group (Spec.H) HARDWARE FUNCTIONAL DESCRIPTION Pin name Signal name I/O VCC,VSS Power supply I CNVSS CNVSS I RESET Reset input I XIN Clock input I XOUT Clock output O AVSS Analog power supply input VREF Reference voltage input I P00–P07,P10–P17, I/O port I/O P20–P27,P30–P37, P40–P43,P50–P57, P60–P67 P44 RxD input I P45 TxD output O P46 SCLK input I P47 BUSY output O Table 17 Description of pin function (Flash Memory Serial I/O Mode 1) Function Apply 2.7 to 5.5 V to the Vcc pin and 0 V to the Vss pin. After input of port is set, input “H” level. Reset input pin. To reset the microcomputer, RESET pin should be held at an “L” level for 16 cycles or more of XIN. Connect an oscillation circuit between the XIN and XOUT pins. As for the connection method, refer to the “clock generating circuit”. Connect AVss to Vss. Apply reference voltage of A/D to this pin. Input “L” or “H” level, or keep open. Serial data input pin. Serial data output pin. Serial clock input pin. BUSY signal output pin.
