ROBOOT communication interface

---

Detailed Description

Purpose.

The purpose of this interface is to provide hardware-specific communication functions, that are used to send the bootloader image to the target.

Realization.

The realization of this interface is optional. You only need this is if you want to use one of the communication protocols that are shipped with ROBOOT.

Functions
void	CommHwInit (void)
void	CommHwDeinit (void)
void	CommHwSendByte (uint8_t a_byte)
int16_t	CommHwGetByte (void)
void	MCUBusyDelay (void)
