CC Microcontroller Reset
NOTE: See sheet 10 in the schematics for the reset circuitry.
The Am186CC microcontroller requires the RES
input to be asserted for at least
1 ms to allow the internal circuitry to stabilize. The Am186CC microcontroller
router reference design uses an external device that monitors the 3.3-V V
CC
to
provide a reset output with an internal 21-ms RC delay to drive the 3.3-V RES
input to the Am186CC microcontroller. Depressing the reset switch (SW1 at
location E-9) causes a system reset without cycling power.
