Parallax SX Embedded Controller Architecture

• Ports
• File Registers +
• Interrupts
• Clocks (resonators / crystals / RC / external)
• Power
• EMI

Also:

• Device Specific Information
• Fusex (device options)
• Cracking / Guarding SXs

Notes:

• the SX can reset themselves because power up sets all pins to input so the reset pulse applied by an output pin will not continusly reset.
• Read/Modify/Write problems get worse at high speeds and also get worse at lower operating voltages
