Functions
static uint8_t	avr_regbit_set (avr_t *avr, avr_regbit_t rb)
	Set/get/clear io register bits in one operation. More...
static uint8_t	avr_regbit_setto (avr_t *avr, avr_regbit_t rb, uint8_t v)
static uint8_t	avr_regbit_setto_raw (avr_t *avr, avr_regbit_t rb, uint8_t v)
	Set the 'raw' bits, if 'v' is the unshifted value of the bits. More...
static uint8_t	avr_regbit_get (avr_t *avr, avr_regbit_t rb)
static uint8_t	avr_regbit_from_value (avr_t *avr, avr_regbit_t rb, uint8_t value)
	Using regbit from value eliminates some of the set to test then clear register operations. More...
static uint8_t	avr_regbit_get_raw (avr_t *avr, avr_regbit_t rb)
	Return the bit(s) 'in position' instead of zero based. More...
static uint8_t	avr_regbit_clear (avr_t *avr, avr_regbit_t rb)
static uint8_t	avr_regbit_get_array (avr_t *avr, avr_regbit_t *rb, int count)
	This reads the bits for an array of avr_regbit_t, make up a "byte" with them. More...
static void	avr_regbit_set_array_from_value (avr_t *avr, avr_regbit_t *rb, uint8_t count, uint8_t value)
	Does the reverse of avr_regbit_get_array. More...
