26.5.12.5 RNG Interrupt Status Register (RNGISR)
The Interrupt Status Register indicates which unmasked errors have occurred and have generated
error interrupts to the channel. Each bit in this register can only be set if the corresponding bit of
the RNG Interrupt Mask Register is zero (see Section 26.4.7.6, RNG Interrupt Mask Register, on
page 26-65). If the RNG Interrupt Status Register is non-zero, the RNG halts and the RNG error
interrupt signal is asserted to the controller (see Section 26.4.7.5, RNG Interrupt Status Register,
on page 26-64). In addition, if the RNG is being operated through channel-controlled access, then
an interrupt signal is generated to the channel to which this EU is assigned. The EU error bit is set
in the channel pointer Status Register (see Section 26.5.5.2, Channel Pointer Status Registers
(CPSR[1–4]), on page 26-92) and generates a channel error interrupt to the controller. If the
Interrupt Status Register is written from the core processor, 1s in the value written are recorded in
the Interrupt Status Register if the corresponding bit is unmasked in the Interrupt Mask Register.

Reset Done
This status bit, when high, indicates that the RNG has completed its reset
sequence.
Note:
The reset value of RD is 0, but it typically switches to 1 by the time
a user checks the register, indicating the EU is ready for
operation.

Reset in progress.
