// interface.
// (see CPU_ID.USER_VERSION field in the documentation)

// Include/Exclude Watchdog timer

// Input synchronizers
//-------------------------------------------------------
// In some cases, the asynchronous input ports might
// already be synchronized externally.
// If an extensive CDC design review showed that this
// is really the case,  the individual synchronizers
// can be disabled with the following defines.
//
// Notes:
//        - all three signals are all sampled in the MCLK domain
//
//        - the dbg_en signal reset the debug interface
//         when 0. Therefore make sure it is glitch free.

// Peripheral Memory Space:
//-------------------------------------------------------
// The original MSP430 architecture map the peripherals
// from 0x0000 to 0x01FF (i.e. 512B of the memory space).
// The following defines allow you to expand this space
// up to 32 kB (i.e. from 0x0000 to 0x7fff).
// As a consequence, the data memory mapping will be
// shifted up and a custom linker script will therefore
// be required by the GCC compiler.
