Pending command code
Whenever a command code is written by CPU, a "command transfer"
will be induced immediately during "ECP forward transferring". If CMD
contains a command code not been transferred yet, a "command
pended" status (CMDtrue) is echoed in DSR[7]. "Reset device" or
"CPU read CMD" or the pended command code is finished
transferring, the CMDtrue will also be cleared.
