| /// !Purpose | |
| /// | |
| /// This module provides definitions and functions for using the Debug Unit | |
| /// (DBGU). | |
| /// | |
| /// It also overloads the fputc(), fputs() & putchar() functions so the printf() | |
| /// method outputs its data on the DBGU. This behavior can be suppressed by | |
| /// defining NOFPUT during compilation. | |
| /// | |
| /// !Usage | |
| /// | |
| /// -# Enable the DBGU pins (see pio & board.h). | |
| /// -# Configure the DBGU using DBGU_Configure with the desired operating mode. | |
| /// -# Send characters using DBGU_PutChar() or the printf() method. | |
| /// -# Receive characters using DBGU_GetChar(). | |
| /// | |
| /// \note Unless specified, all the functions defined here operate synchronously; | |
| /// i.e. they all wait the data is sent/received before returning. | |
