Functions
void	put_OCD (U8 val)
	This macro is used to output a character on OCD/Serial Debug Interface when SOFT_OCD switch enabled, character is output as is => VT100 or Hyperterminal usage when switch disabled, character are ORed with 0x80 to distinguish from debug status byte output from OCD hardware => OCD dongle usage.
void	trace_u32 (U32 val)
	Fonction used to display a byte value in the decimal form (16 bits) on OCD/Serial Debug Interface.

void put_OCD (  U8  val  )  [static]

This macro is used to output a character on OCD/Serial Debug Interface when SOFT_OCD switch enabled, character is output as is => VT100 or Hyperterminal usage when switch disabled, character are ORed with 0x80 to distinguish from debug status byte output from OCD hardware => OCD dongle usage. Parameters: val  character to output on SDI Definition at line 71 of file debug.c. Referenced by trace(), trace_hex(), trace_u16(), trace_u32(), and trace_u8(). { while( OSCON & MSK_OCDTBSY ); # ifdef SOFT_OCD OSBUF = val; # else OSBUF = (val|0x80); # endif }
