HDMI Tx Interrupt Polarity
This register is used to configure various logical operations which are available to the user when using the HDMI Tx interrupts.
tx_int_pol[1:0]
, IO Map,
Address 0x1A76[1:0]
This signal is used to control the TX interrupt polarity.
Function
tx_int_pol[1:0]
Description
00 (default)
Tx interrupt is logical AND of Tx1/Tx2 interrupts
01
Tx interrupt is inverted logical AND of Tx1/Tx2 interrupts
10
Tx interrupt is logical OR of Tx1/Tx2 interrupts
11
Tx interrupt is inverted logical OR of Tx1/Tx2 interrupts
