SOCParPort-APB
Parallel-Printer Port Core
SOC-ParPort-APB 8-bit bi-directional parallel port compatible with printers. status command registers provide information about state printer inputs outputs, while control register allows programmer control printer outputs. SOC-ParPort-APB bi-directional modes control parallel port. mode allows select register control parallel port direction while other mode allows direction control register control direction.
SOC-ParPort-APB provides various printer signals which monitored controlled through status, command, control registers. Printer input signals (errorN, slct, ackN, busyN) monitored through status register, printer outputs (strobeN, autoFdXtN, init, slctInN) controlled monitored through control command registers respectively. SOC-ParPort-APB also provides interrupt modes, "latch" "acknowledge". "latch" mode, interrupt asserted falling edge ackN input will remain until status register read. "acknowledge" mode, interrupt tracks ackN input. When ackN low, interrupt will asserted, when ackN high, interrupt will clear. SOC-ParPort-APB also used general purpose I/O.
