12.4.1.9
The EU go 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, per the contents of the
parameter memories listed below. This register has no data size, and during the write operation, the host
data bus is not read. Hence, any data value is accepted. Normally, a write operation with a zero data value
is performed. Reading from this register is not meaningful, but a zero value is always returned, and no error
is generated.
12.4.1.10 PKEU Parameter Memories
The PKEU uses four 2048-bit memories to receive and store operands for the arithmetic operations the
PKEU will be 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.
