45 / 240 page ![]() 2.0 Device Architecture and Configuration (Continued) 45 www.national.com Table 15. PSLDC0,1 Configuration Options 2.7 REGISTER TYPE ABBREVIATIONS The following abbreviations are used to indicate the Register Type: q R/W = Read/Write q R = Read from a specific address returns the value of a specific register. Write to the same address is to a different register. q W=Write q RO = Read Only q R/W1C = Read/Write 1 to Clear. Writing 1 to a bit clears it to 0. Writing 0 has no effect. 2.8 SUPERI/O CONFIGURATION REGISTERS This section describes the SuperI/O configuration and ID registers (those registers with first level indexes in the range of 20h - 2Eh). See Table 16 for a summary and directory of these registers. Table 16.
