S12 bit field define problem

[赵子成]

Hi everyone,

I defined a variable via bit field way as follow:

typedef struct stAbbrTime_t

{

UINT32 Sec : 6;
UINT32 Min : 6;
UINT32 Hour : 5;
UINT32 Day : 5;
UINT32 Month : 4;
UINT32 Year : 6;

}ST_ABBR_TIME;

I think this variable must be 4 bytes length, but in fact it occupy 5 bytes as follow:

I don't know why.

The bit field settings in CW5.1 is as follow(I use the default setting)

Thank you.
