SX Microcontroller Program Flow Methods

• Jumps and Calls
• Compare a Register <, >, <=, or >= a constant or a register
• Test if a value is in or out of a range
• Delays
• Long term timers without interrupts
• Multitasking / Context Switching
• Software Stacks
• Parsing the radix from "B" for binary, etc..
• PIC Code generator  for keyword matching from a serial text stream by Nikolai Golovchenko Wow!

Notes:

Despite this not being documented anywhere, adding, or-ing, and-ing, moving, etc... an 8 bit value to the PC (bits 0..7) also results in CLEARING the 9th bit (bit 8) of the PC. So you can only do relative or computed jumps into the first half page of each page. Just like calls
