FOXBORO FBM237 P0914XS Monitor Module

Serial Interface Programming Considerations ❏ The MVME167 board hardware ties the DTR signal from the CD2401 to the pin labeled RTS at connector P2. Likewise, RTS from the CD2401 is tied to DTR on P2. Therefore, when programming the CD2401, assert DTR when you want RTS, and RTS when you want DTR. 

❏ The interface provided by the PCCchip2 allows the 16-bit CD2401 to appear at contiguous addresses 

❏ Accesses to the CD2401 must be 8 or 16 bits: 32-bit accesses are not permitted. 

❏ The CD2401 supports DMA operations to local memory. ❏ Because the CD2401 does not support a retry operation necessary to break VMEbus lockup conditions, the CD2401 DMA controllers should not be programmed to access the VMEbus.

Parallel Port Interface 

The PCCchip2 provides an 8-bit bidirectional parallel port. This port may be used as a Centronics-compatible parallel printer port or as a general parallel I/O port. All eight bits of the port must be either inputs or outputs (no individual bit selection). In addition to the 8 bits of data, there are two control pins and five status pins.Each of the status pins can generate an interrupt to the MPU in any of the following programmable conditions: ❏ high level ❏ low level ❏ high-to-low transition ❏ low-to-high transition

The PCCchip2 provides an auto-strobe 

feature similar to that of the MVME147 PCC. 

❏ In auto-strobe mode, after a write to the Printer Data Register, the PCCchip2 automatically asserts the STROBE* pin for a selected time specified by the Printer Fast Strobe control bit. ❏ In manual mode, the Printer Strobe control bit directly controls the state of the STROBE* pin
