Hello,

I had a customer point out to me that the deglitch times for UCGLITx are defined in the datasheet as follows:

However the comments in the MSP430FR2355.h include file suggest some different values:

/* UCA0CTLW1 Control Bits */
#define UCGLIT (0x0003) /* Deglitch time */
#define UCGLIT_L (0x0003)
#define UCGLIT0 (0x0001) /* Deglitch time */
#define UCGLIT0_L (0x0001)
#define UCGLIT1 (0x0002) /* Deglitch time */
#define UCGLIT1_L (0x0002)
#define UCGLIT_0 (0x0000) /* Approximately 2 ns (equivalent of 1 delay element) */
#define UCGLIT_1 (0x0001) /* Approximately 50 ns */
#define UCGLIT_1_L (0x0001)
#define UCGLIT_2 (0x0002) /* Approximately 100 ns */
#define UCGLIT_2_L (0x0002)
#define UCGLIT_3 (0x0003) /* Approximately 200 ns */
#define UCGLIT_3_L (0x0003)

Which timings are the ones the customer should go with?
