STP2000QFP
32-bit SBus Master I/O Controller
Master I/O
July 1997
1. The Parallel Port control and data line direction bits, (for example, P_*_DIR), are gang programmed by the DIR bit of the Transfer
Control Register.
DIR=0 sets transfer direction away from the STP2000 (P_D_DIR=P_DS_DIR=1; P_BSY_DIR=P_ACK_DIR=0); DIR=1 sets transfer
direction towards the STP2000 (P_D_DIR=P_DS_DIR=0; P_BSY_DIR=P_ACK_DIR=1).
