Detailed Description

Cortex CMSIS style definition of MSP430 registers.

Todo: This file is incomplete, not all registers are listed. Further There are probably some inconsistencies throughout the MSP430 family which need to be addressed.

Data Structures
struct	msp430_port_t
	Common MSP GPIO Port Registers. More...

struct	msp430_port_p3_p6_t
	GPIO Port 3..6 (without interrupt functionality) More...

struct	msp430_timer_t
	Timer peripheral registers. More...

#define	REG8 volatile uint8_t
	Shortcut to specify 8-bit wide registers.

#define	REG16 volatile uint16_t
	Shortcut to specify 16-bit wide registers.

Timer SSEL Values
When using the macros in the vendor header files such as TASSEL_0 the actually used clock is non-obvious. Hence, provide aliases with obvious names.
#define	TXSSEL_TXCLK TASSEL_0
	External TxCLK as clock source.

#define	TXSSEL_ACLK TASSEL_1
	Auxiliary clock as clock source.

#define	TXSSEL_SMCLK TASSEL_2
	Sub-system master clock as clock source.

#define	TXSSEL_INCLK TASSEL_3
	External INCLK as clock source.

Timer Input Divider Values
The vendor header macros are again non-obvious in their naming, so provide better alias names.
#define	TXID_DIV_1 ID_0
	Input Divider: Divide by 1.

#define	TXID_DIV_2 ID_1
	Input Divider: Divide by 2.

#define	TXID_DIV_4 ID_2
	Input Divider: Divide by 4.

#define	TXID_DIV_8 ID_3
	Input Divider: Divide by 8.

#define	TXID_DIV_Msk ID_3
	Mask to get the TXID field.

#define	TXID_DIV_Pos 6U
	Position of the TXID field.

#define	TXID_DIV_MAX 3
	Maximum configuration value in the TXID field.

Timer Mode Control Values
The vendor header macros are again non-obvious in their naming, so provide better alies names.
#define	TXMC_STOP MC_0
	Stop Mode.

#define	TXMC_UP MC_1
	Up to CCR0 Mode.

#define	TXMC_CONT MC_2
	Continuous Mode.

#define	TXMC_UP_DOWN MC_3
	Up/Down Mode.

#define	TXMC_MASK MC_3
	Bitmask to retrieve MC field.
