msp430 talk
several different families each with ranges of performance and features from tiny to all-encompassing

gobs of applications

von-neumann common bus connects CPU to all mem and periph
sophistocated clock gen, can turn off individual clocks

voltage range for msp430 is variable, but high current required for writing of flash, so won't work if battery low

will learn how to use timers in real world operations
USARTs - universal sync async rx tx

16bit risc
16bit register file elims single accum bottleneck
high bw 16bit data and address bus with no paging
27 instructions and 7 addressing modes
R0 is used as PC
single cycle reg ops w/ full access
R1 reserved for stack pointer
direct mem xfer designed for modern programming
low power

status reg (R2) used as src or dst reg, can be use in register mode only addressed with word inst
constant generation, R2, R3, some kind of crazy flying around

on a side note, milenkovich likes to stand in front of the fucking text on the board
it's starting to piss me off

CG allows for 24 emulated instructions

R4-R15 are general purpose

ADD.B R5,0(R6)		add value in R5 to value at mem address R6 (lower byte)

addressing modes
register
indexed
symbolic(pc rel)
absolute
indirect
ind autoinc, inc depends on op, some are word size (+=2), some are byte size (++)
immediate

indirect and immediate only viable for src operands
2 bits (and address field) to encode 7 modes....
