Function Documentation

◆ sys_get_awake_key()

uint16_t sys_get_awake_key ( void )

◆ sys_get_sleep_time()

uint16_t sys_get_sleep_time ( void )

◆ sys_get_tick_count()

uint32_t sys_get_tick_count ( void )

Read the current tick count.

Under FreyaBIOS, one tick equals one frame. Note that the WonderSwan runs at 75Hz.

Returns: uint32_t The current tick count.

◆ sys_get_version()

uint16_t sys_get_version ( void )

◆ sys_interrupt_reset_hook()

void sys_interrupt_reset_hook	(	uint8_t	id,
		intvector_t *	old_vector )

◆ sys_interrupt_set_hook()

void sys_interrupt_set_hook	(	uint8_t	id,
		intvector_t *	new_vector,
		intvector_t *	old_vector )

◆ sys_set_awake_key()

void sys_set_awake_key ( uint16_t key )

◆ sys_set_keepalive_int()

void sys_set_keepalive_int ( uint16_t value )

◆ sys_set_sleep_time()

void sys_set_sleep_time ( uint16_t time )

◆ sys_sleep()

void sys_sleep ( void )

◆ sys_wait()

void sys_wait ( uint16_t v )
