1.4.1. Interrupt Enable Register

Use the Interrupt Enable register to enable or disable interrupts.
Note: These enable bits do not prevent the value of interrupt status bit from showing up in ISR, they only prevent the interrupt status bit from causing interrupt output assertion via IRQ signal.
Table 6.  Interrupt Enable Register
Bit Fields Access Default Value Description
31:8 Reserved
9 EN_RD_RSP_FIFO_WHEN_EMPTY R/W 0x0 The enable interrupt bit for read response FIFO when empty detection.
  • 1: Enable the read response FIFO when empty detection interrupt bit.
  • 0: Disable the read response FIFO when empty detection interrupt bit.
8 EN_WR_CMD_FIFO_WHEN_FULL R/W 0x0 The enable interrupt bit for write command FIFO when full detection.
  • 1: Enable the write command FIFO when full interrupt bit
  • 0: Disable the write command FIFO when full interrupt bit
7 EN_CRYPTO_ERROR_RECOVERY_PROGRESS 3 R/W 0x0 The enable interrupt bit for crypto service error recovery progress status.
  • 1: Enable the crypto service error recovery progress interrupt
