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.

USART clock selection
The vendor header files expose clock configurations selection field as one bitmask per bit. This is pretty hard to read in the code, so we provide alias with better names.
#define	UXTCTL_SSEL_UCLKI 0
	Clock USART using UCLKI clock.

#define	UXTCTL_SSEL_ACLK SSEL0
	Clock USART using auxiliary clock.

#define	UXTCTL_SSEL_SMCLK SSEL1
	Clock USART using sub-system master clock.

#define	UXTCTL_SSEL_MASK (SSEL0 \| SSEL1)
	Mask to retrieve SSEL field.

Typing of base register objects
msp430_usart_sfr_t	USART_0_SFR
	USART 0 SFR register map.

msp430_usart_sfr_t	USART_1_SFR
	USART 1 SFR register map.

msp430_usart_t	USART_0
	USART 0 register map.

msp430_usart_t	USART_1
	USART 1 register map.
