Fixed-Width Integer Types

Typedef names that designate signed and unsigned integer types with an exact width.

Attention: The types for 24-bit objects are only supported when using PIC devices and MPLAB XC8. The types for 64-bit objects are not supported when using 8-bit AVR, Baseline, or non-enhanced Mid-range PIC devices with MPLAB XC8.
