11 / 43 page  μPD720201/μPD720202 2. PIN FUNCTION R19DS0047EJ0500 Rev. 5.00 Page 11 of 40 Jan. 17, 2013 2.3.4 SPI Interface Table 2-7. SPI Interface Pin Name 720201 Pin No. 720202 Pin No. Type Active Level Function SPISCK 18 15 O (3.3 V Output) − SPI serial flash ROM clock signal. When the external serial ROM is not mounted, this signal should be pulled down through a pull- down resistor. SPICSB 17 14 O (3.3 V Output) − SPI serial flash ROM chip select signal. When the external serial ROM is not mounted, this signal should be pulled down through a pull- down resistor. SPISI 19 16 O (3.3 V Output) − SPI serial flash ROM slave input signal. When the external serial ROM is not mounted, this signal should be pulled down through a pull- down resistor. SPISO 16 13 I (3.3 V Input) - SPI serial flash ROM slave output signal. This signal should be pulled up through a pull-up resistor in all cases. |
