MODID Signal Termination
W26 configures the MODID signal termination for Slot 0/Non-Slot 0 operation. In the default
configuration for Slot 0 operation (Figure 2-2a), W26 causes the MODID signal to be terminated
with a 16.9 k
Ω
pull-up resistor. When configured for Non-Slot 0 operation (Figure 2-2b), W26
causes the MODID signal to be terminated with an 825
Ω
pull-down resistor.
