Return: 0 = success, 1 = fail
Parameters: •
rx_idx
—Sink instance index (0 - 3)
•
rx_base_addr
—RX base address
•
rx_irq_id
—RX IRQ ID
•
rx_irq_num—
RX IRQ number
•
rx_num_of_sinks
—Number of streaming sinks used (1 - 4)
•
options
—OR-ed options for this instance or 0 if unused
Description: This function declares a sink (RX) instance to the system library. It should be
invoked once for each existing sink instance, starting from
rx_idx = 0
. After all
sinks have been declared, invoke
btc_dprx_syslib_ init ( )
.
Example:
btc_dprx_syslib_add_rx (0, BITEC_DP_0_AV_RX_CONTROL_BASE, BITEC_DP_
0_AV_RX_CONTROL_IRQ_INTERRUPT_CONTROLLER_ID, BITEC_DP_0_AV_RX_
CONTROL_IRQ, 2, BTC_DPRX_OPT_DISABLE_ERRMON);

Prototype:
void btc_dprx_syslib_info(
BYTE *max_sink_num,
BYTE *mst_support)
Thread-safe: Yes
Available from ISR: Yes
Include:
< btc_dprx_syslib.h >
Return: None
Parameters: •
max_sink_num
—Pointer for maximum number of sinks supported
•
mst_support
—Pointer for MST support
Description: This function returns information about the system library capabilities. On return,
max_sink_num
is set with the maximum number of supported sink instances (1 - 4)
and
mst_support
is set to zero if MST is not supported and 1 if it is supported.
