The ICOP-0101-V2 is a 48-bit digital I/O module. The module can be used together with TTL level input /output circuitry. Its 48 bits are arranged in two 24-bit digital I/O groups. Each group emulates an 8255 PPI (programmable peripheral interface) mode 0 but has a higher driving capacity than the 8255 PPI. Each 24-bit group is divided into three 8-bit ports. A port can be configured to function as input or output.
- 48-BIT 數位 I/O 線(2組)
- 集團模擬 8225 PPI 模式 0
- 緩衝電路的驅動能力比 8255 更强
- 端口 C 的第 0 位可以產生一個中斷到 IRQ 2, 3, 4, 5, 6, 7
- 上升/下降沿的中段觸發器
- 輸出狀態回讀
- 與 OPT 0-22 I/O 模組機架的引腳兼容
- 傳輸速率: 300 KB/秒。(典型)
