How can i concate the 8 bits of the struc to one var

[The Puma]

// Defines seconds register (RESET STATE: ???? ????)
struct {
byte UNITS_BCD :4; // Unit seconds BCD format
byte TENS :3; // Ten seconds, 0 to 5 binary
byte NOT_UNUSED :1; // NOT USED
} SECONDSREG;

time[0]=hexd2decD(SECONDSREG.TENS);
time[1]=hexd2decD(SECONDSREG.UNITS_BCD);

Now there are two 8 bit vars (time[0]+time[1])
How can i put these together on one var (time[0])

See the make16() function in the CCS manual.

Thats make an 16bit value

But i need an 8bit var

UNITS_BCD = 4 bit
TENS = 3 bit
NOT USED = 1 bit

I will concate the 3 types together and put it in an 8 bit variable
time[0]

OK, I guess I misread your post.

It looks like you could use bcd2bin() to convert SECONDSREG to
an 8-bit integer. Example:
