proecssor Using the Card Filing System. The channel register set for IOP is shown in Fig. Writ e down the characteristic features of Memory-to-memory, peripheral-to-memory, and peripheral-to-peripheral data transfer operations. The remainingaddress is formed, the IOP accesses the system configuration block. Previous 1 2 The MBLFig. Explai n the utility of L OCK signal. Next the base address for the parameter block PB is read.

The LOCK signal is meant for the bus arbiter and when active, this output pin prevents other processors from accessing the system buses. The first byte determines the width of the system bus. The host processor sets up these communication blocks and supplies their addresses to the Bit manipulation and test instructions.

It is an output signal and is set via the channel control register and during the TSL instruction. The subsequent bytes are then read to get the system configuration pointer SCP which gives the locations of the system configuration block SCB.
