10.7.7.9
The PKEU end of message register in the PKEU is used to indicate the start of a new computation. Writing
to this register causes the PKEU to execute the function requested by the ROUTINE field, according to the
contents of the parameter memories described in
The value written to this register does not matter: ordinarily, all zeros are written. A read of this register
always returns a zero value.
Offset 0x3_C050
10.7.7.10 PKEU Parameter Memories
The PKEU uses four 4096-bit memories to receive and store operands for the arithmetic operations the
PKEU is asked to perform. In addition, results are stored in one particular parameter memory.
Data addressing within these memories is big-endian, that is, the most significant byte is stored in the
lowest address.
10.7.7.10.1 PKEU Parameter Memory A
This 4096 bit memory is used typically as an input parameter memory space. For modular arithmetic
routines, this memory operates as one of the operands of the desired function. For elliptic curve routines,
this memory is segmented into four 1024 bit memories, and is used to specify particular curve parameters
and input values.
