Change Register Bit Field Configurations using Bit Unions

The union declaration of the registers offers access to register bits and bit fields without affecting the rest of the register.

/* using a hex value */
T0CON0bits.T0OUTPS = 0x7;     /* Select 1:10 postscaler */
/* using a binary value */
T0CON0bits.T0OUTPS = 0b0111;  /* Select 1:10 postscaler */

This is the recommended way of updating bit field register configurations, which is simpler than the alternative options.
