Manufacturer:ON Description:Pin 108 is also a dualCfunction pin, designated SMMBZ5248ELT1GEMMBZ5248ELT1GWR/ RDYPOL. In ISACBUS compatible operating modes 0, 1 and 2 (when one or both of mode pins 91 and 92 are tied low), pin 108 serves as the system memory write input (SMMBZ5248ELT1GEMMBZ5248ELT1GWR) to support writing to a Flash Boot ROMMBZ5248ELT1G (For this purpose, it should be connected to the system memory write pin of the PC/XT/AT/ISA bus connector.) In these three modes, the MMBZ5248ELT1GB will provide chip select pulses to the boot ROMMBZ5248ELT1G for both read and write operations. In mode 3 (pins 91 and 92 both tied high), this function is disabled as no boot ROMMBZ5248ELT1G support is available in this mode. In mode 3, pin 108 reverts to its original role in the MMBZ5248ELT1GA as RDYPOL, an input to select the polarity of the ready pin. |
