- Fix sim driver so that it can handle two bytes read/write.
- Add error message regarding odd size write to sim driver.
- Fix simio_timer constructor so that can accept size.
- Fix simio_timer so that we read/write channels' registers.
The "regs" command indicates when the PC is sitting on an enabled
breakpoint. The simulator emits debug output when a watchpoint is
triggered by a simulated instruction.
The same rules for PC apply to the stack pointer. Even when byte-mode
instructions are executed, the stack pointer is incremented by a whole
word when using the indirect increment addressing mode.
If the source operand is indexed, and the destination is symbolic (PC +
index), then the base for the destination index is the program counter
*after* having fetched the source index.
Also, the addition of the index is done modulo 2^16 if the base points
within the lower 64 kB of memory.
Ctrl+C handling is done in ctrlc.c, and a break condition now persists
until the interactive reader begins to process the next command. The
condition is cleared by calling ctrlc_clear().
