File Size : 116 KB Manufacturer:74 Description:Power Supply Return. External TTL Clock Input (See Table 2) An interrupt request is asserted by the TPUART when an enabled condition has occurred in the Status Register. This is an active low, open drain output. This pin has an internal pullup register. During processor to TPUART communications, this input is used to indicate which internal register will be selected for access by the processor. When this input is low, data can be written to the TX Holding Buffer or data can be read from the RX Holding Register. When this input is high control words can be written to the Control Register or status information can be read from the Status Register. This input is the receiver serial data. A high to low transition is required to initiate data reception. This output is the transmitted serial data from the TPUART. When a transmission is concluded, the TX line will always return to the mark (High) state. This control pin is an input only pin. It can be programmed to perform the functions of CTS or DSR/DCD. This control pin can be programmed to be either an input or an output. When in input mode, this pin can perform the functions of DSR/DCD. When in output mode, this pin can perform the functions of DTR or RTS. +5V Supply Voltage
