#define __MSP430_BASEADDRESS_WDT_A__ 0x0150

#define WDTCTL_               0x015C    /* Watchdog Timer Control */

What exactly is wrong about these symbols?

Hello,

Thank you for noticing this, if you were to use WDT_A_BASE with a value of 150h then you would be making changes to the CRC16 register instead of the Watchdog. I will submit a bug report so that this is fixed in later revisions. In the meantime I suggest you use WDTCTL instead of WDT_A_BASE.

Regards,
Ryan

This is not a bug.

The base address is aligned to a multiple of 0x10 so that it can be described in the TLV peripheral descriptor. The control register is then defined as having the offset 0xC from that base.
