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.

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.
