Data lines have weak internal pull-up drivers. External bus loading can overcome the weak internal pull-
up drivers on data bus lines, and hold pins low during reset. Use an active device to hold data bus lines
low. Data bus configuration logic must release the bus before the first bus cycle after reset to prevent
conflict with external memory devices. The first bus cycle occurs ten CLKOUT cycles after RESET is
released. If external mode selection logic causes a conflict of this type, an isolation resistor on the driven
lines may be required.
3.8.2 Reset States of SIML Pins
Generally, while RESET is asserted, SIML pins either go to an inactive high-impedance state or are
driven to their inactive states. After RESET is released, mode selection occurs and reset exception pro-
cessing begins. Pins configured as inputs must be driven to the desired active state. Pull-up or pull-
down circuitry may be necessary. Pins configured as outputs begin to function after RESET is released.
Table 32 is a summary of SIML pin states during reset.
