The Interrupt Enable register (IER) is described in the following table and allows you to selectively generate an interrupt at the output port for each error/status bit in the ISR. An IER bit set to 0 does not inhibit an error/status condition from being captured, but inhibits it from generating an interrupt.

Table 1. Interrupt Enable Register (0x28)
Bits Name Reset Value Access Description
31 Frame Received 0x0 R/W

Set bits in this register to 1 to generate the required interrupts. Set to 0 to disable the interrupt.

For a description of the specific interrupt you are enabling/disabling in this register see the ISR descriptions in Interrupt Status Register.
30 VCX Frame Error 0x0 R/W Set to 1 to generate the VCX Frame Error interrupt.
29 RX_Skewcalhs 0x0 R/W Set to 1 to generate the rxskecalhs interrupt.
28 YUV420 WC Error 0x0 R/W Set to 1 to generate the YUV420 WC Error interrupt.
27 Pending write in internal FIFO 0x0 R/W

Set bits in this register to 1 to generate the required interrupts. Set to 0 to disable the interrupt.

For a description of the specific interrupt you are enabling/disabling in this register see the ISR descriptions in Interrupt Status Register.
