20.6.7 CRYP interrupt mask set/clear register (CRYP_IMSCR)
Address offset: 0x14
Reset value: 0x0000 0000
The CRYP_IMSCR register is the interrupt mask set or clear register. It is a read/write
register. On a read operation, this register gives the current value of the mask on the
relevant interrupt. Writing 1 to the particular bit sets the mask, enabling the interrupt to be
read. Writing 0 to this bit clears the corresponding mask. All the bits are cleared to 0 when
the peripheral is reset.
