Description
System Reset Input
A system reset should be at least as long as one clock cycle of the slowest
of DOTCLK, XTALIN or SCLK. RESET# should be active for at least 1 ms.
Crystal Oscillator Connection
This pin is the crystal input for the on-chip reference oscillator or a CMOS
clock input from an external reference source. It should be 14.318 MHz.
Crystal Oscillator Connection
This pin is the crystal output for the on-chip reference oscillator. If an exter-
nal clock is used, leave this pin unconnected.
General Purpose Inputs/Outputs
Each GPIO pin can be configured independently as an input or output. For
further programming information refer to Section 3.2.13 “General Purpose
I/O Pins” on page 38.
