The SIM clock synthesizer provides clock signals to the other MCU modules. After the
clock is running and MSTRST is asserted for at least four clock cycles, these modules
reset. V
cles take. Worst case is approximately 15 milliseconds. During this period, module
port pins may be in an indeterminate state. While input-only pins can be put in a known
state by external pull-up resistors, external logic on input/output or output-only pins
during this time must condition the lines. Active drivers require high-impedance buffers
or isolation resistors to prevent conflict.

RESET, V
Asserting the three-state control (TSC) input causes the MCU to put all output drivers
in a disabled, high-impedance state. The signal must remain asserted for approxi-
mately ten clock cycles in order for drivers to change state.
When the internal clock synthesizer is used (MODCLK held high during reset), synthe-
sizer ramp-up time affects how long the ten cycles take. Worst case is approximately
20 milliseconds from TSC assertion.
When an external clock signal is applied (MODCLK held low during reset), pins go to
high-impedance state as soon after TSC assertion as approximately ten clock pulses
have been applied to the EXTAL pin.
