Texas Instruments , Ver. 3, 1997 - 428 p. - The MSP430 is a 16-bit microcomputer having special features not commonly available with other microcomputers:
· Complete system on-chip (LCD, ADC, I/Os, ROM, RAM, Watchdog, UART, Basic
Timer)
· Extremely low power consumption: only 4.2nWs/instruction max.
· High speed (300ns/instruction @ 3.3MHz with register, register addressing mode)
· RISC structure (27 core instructions)
· Orthogonal architecture (any instruction with any addressing mode)
· Seven addressing modes for the source operand
· Four addressing modes for the destination operand
· Constant generator for the most often used constants (-1, 0, 1, 2, 4, 8)
· Only one crystal necessary due to a Frequency Locked Loop (FLL) oscillator
· Full real time capability: the stable, nominal system clock frequency is reached after only six clocks when woken-up from Low Power Mode 3: this means no waiting for the
coming-up of the main crystal. These features make it very easy to program the MSP430 in assembler or in C-language. For example, despite the low instruction count of only 27, the MSP430 is capable of emulating almost the complete instruction set of the legendary PDP11.
