Tews TPMC681
PMC	PowerPC	v. 4.0
Digital I/O

Tews' TPMC681 is a standard single-width 32-bit PMC module offering 64 ESD-protected TTL I/Os. Each line is individually programmable as input, output or tri-state. The receivers are always enabled, which allows determining the state of each I/O line at any time. This can be used as read back function for lines configured as outputs. Each TTL I/O line has a pull-up resistor. The pull-up voltage is selectable to be either +3.3V or +5V.

Each input can generate an interrupt. Signal edge handling is programmable to interrupt on rising and/or falling edge of an input signal. Interrupts can be enabled and disabled for each bit. For interrupt source detection the status of each bit can be read from interrupt status registers.

The TPMC681 provides front panel I/O via a HD68 SCSI-3 type connector and rear panel I/O via P14.
