Detailed Description

Tracks call stack for intelligent stepping.

The 65816 uses these instructions for subroutine calls:

• JSR (opcode 0x20): Jump to Subroutine (16-bit address, pushes PC+2)
• JSL (opcode 0x22): Jump to Subroutine Long (24-bit address, pushes PB + PC+3)

And these for returns:

• RTS (opcode 0x60): Return from Subroutine (pulls PC)
• RTL (opcode 0x6B): Return from Subroutine Long (pulls PB + PC)
• RTI (opcode 0x40): Return from Interrupt (pulls status, PC, PB)
