;* DESCRIPTION

;* When including this file in the assembly program file, all I/O register

;* names and I/O register bit names appearing in the data book can be used.

;*

;* The Register names are represented by their hexadecimal addresses.

;*

;* The Register Bit names are represented by their bit number (0-7).

;*

;* Please observe the difference in using the bit names with instructions

;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc"

;* (skip if bit in register set/cleared). The following example illustrates

;* this:

;*

;* in   r16,PORTB               ;read PORTB latch

;* sbr  r16,(1<

;* out  PORTB,r16               ;output to PORTB

;*

;* in   r16,TIFR                ;read the Timer Interrupt Flag Register

;* sbrc r16,TOV0                ;test the overflow flag (use bit#)

;* rjmp TOV0_is_set             ;jump if set

;* ...                          ;otherwise do something else
