4 / 84 page Preliminary W741E20X - 4 - PIN DESCRIPTION SYMBOL I/O FUNCTION XIN I Input pin for oscillator. Connected to crystal or resistor to generate system clock by code option. XOUT O Output pin for oscillator. Connected to crystal or resistor to generate system clock by code option. RA0 −RA2, RA3 (DATA) I/O Input/Output port. Input/output mode specified by port mode 1 register (PM1). When used as output port, can provide high sink current for driving LED. RB0 −RB3 I/O Input/Output port. Input/output mode specified by port mode 2 register (PM2). When used as output port, can provide high sink current for driving LED. RC0 −RC3 I/O Input/Output port. Input/output mode specified by port mode 4 register (PM4). Each pin has an independent interrupt capability in input mode. RD0 −RD3 I/O Input/Output port. Input/output mode specified by port mode 5 register (PM5). RE0/DOUT, RE1/CLKO, RE2/DIN, RE3/CLKI I/O Special input/output port. This port can be configured by software to act as the output of internal port RT or the serial I/O port. When used as output port, can provide high sink current for driving LED. MFP O Output pin only. This pin can output modulating or nonmodulating frequency, or Timer 1 clock output specified by mode register 1 (MR1). INT (MODE) 1 I External interrupt pin. This pin must be tied to VDD through an external resistor. It is a low active and floating input pin. RES (VPP) 1 I System reset pin. This pin must be tied to VDD through an external resistor when it is not used to reset this chip. It is a low active and floating input pin. VDD I Positive power supply (+). VSS I Negative power supply (-). Note: There are internal pull-high resistors in these pins of W741C20X. |
