int st25r3911b_fifo_reload_lvl_get	(	uint8_t *	tx_lvl,
		uint8_t *	rx_lvl
	)

#include <lib/st25r3911b/st25r3911b_common.h>

Get NFC Reader FIFO reload level.

The interrupt trigger level for read/write FIFO water level is configurable, so it must be read to read/write FIFO bytes if necessary. The NFC Reader supports transfer up to ST25R3911B_MAX_TX_LEN, but FIFO is only ST25R3911B_MAX_FIFO_LEN bytes.

Parameters

[out]	tx_lvl	Number of bytes to write to FIFO if a reload is needed.
[out]	rx_lvl	Number of bytes to read to avoid FIFO overflow.

Return values

0	If the operation was successful. Otherwise, a (negative) error code is returned.
