PRESENT_CRYPTO=Absent, PRESENT_SHA=Absent
DCP control register 0
| CHANNEL_INTERRUPT_ENABLE | Per-channel interrupt enable bit 1 (CH0): CH0 2 (CH1): CH1 4 (CH2): CH2 8 (CH3): CH3 |
| ENABLE_CONTEXT_SWITCHING | Enable automatic context switching for the channels |
| ENABLE_CONTEXT_CACHING | The software must set this bit to enable the caching of contexts between the operations |
| GATHER_RESIDUAL_WRITES | The software must set this bit to enable the ragged writes to the unaligned buffers to be gathered between multiple write operations |
| PRESENT_SHA | Indicates whether the SHA1/SHA2 functions are present. 0 (Absent): Absent 1 (Present): Present |
| PRESENT_CRYPTO | Indicates whether the crypto (cipher/hash) functions are present. 0 (Absent): Absent 1 (Present): Present |
| CLKGATE | This bit must be set to zero for a normal operation |
| SFTRST | Set this bit to zero to enable a normal DCP operation |
