Define documentation

#define BN_CFG_LINK_BAUD_RATE
#include <bn_config_link.h>

Specifies transmission rate in bps.

Values not specified in BN_LINK_BAUD_RATE_* macros are not allowed.

#define BN_CFG_LINK_SEND_WAIT
#include <bn_config_link.h>

Specifies how much time the GBA has to wait before sending pending messages.

If this parameter is too low, some messages will be lost, but if it is too high, CPU usage will increase a lot.

#define BN_CFG_LINK_MAX_MESSAGES
#include <bn_config_link.h>

Specifies the maximum number of stored messages for each player.

#define BN_CFG_LINK_MAX_MISSING_MESSAGES
#include <bn_config_link.h>

Specifies the maximum number of missing messages before resetting the communication.
