NOTE:
An external clock from another CMOS-compatible device can drive the
OSC1 input, with the OSC2 pin unconnected, as
The bus frequency (f
the processor clock cycle is two times the f
A logic 0 on the RESET pin forces the MCU to a known startup state. The
RESET pin contains an internal Schmitt trigger as part of its input to
improve noise immunity. See
The IRQ pin is an asynchronous external interrupt pin. The IRQ pin
contains an internal Schmitt trigger as part of its input to improve noise
immunity. See
The TCAP pin is the input capture pin for the on-chip capture/compare
timer. The TCAP pin contains an internal Schmitt trigger as part of its
input to improve noise immunity. See
