Input Operations For input operations (see page page 279), bytes are read
into memory as follows:
•
BYTE input - the first byte in memory was read on the first handshake,
the next byte in memory was read on the second handshake, and so on.
•
WORD input - first and second byte in memory were read on the first
handshake, next two bytes in memory were read on the second
handshake, and so on.
•
LWORd input - first four bytes in memory were read on the first
handshake, next four bytes in memory were read on the second
handshake, and so on.
Note that for
WORD inputs the first byte in memory is considered the most
significant byte and was read on the upper bits (8 through 15). For
LWORd
inputs the first byte was read on bits 24 through 31.
