D0–D7 8–13, I/O Data Bus: Active–High 8-bit bidirectional 3-State data bus. Bit 0 is the LSB and bit 7 is the MSB. All 16, 17 data, command, and status transfers between the CPU and the Octal UART take place over this bus. ...

These clocks may be used by any or all of the receivers and transmitters in the OCTART or may be directed to an I/O pin for miscellaneous use. Counter/Timer programming The counter timer is a 16–bit programmable divider that operates in one of three modes: counter, timer, and time out. ...

... Philips Semiconductors Enhanced octal universal asynchronous receiver/transmitter (Octal UART) the bit time clock (1X clock mode). If RxD is sampled high, the start bit is invalid and the search for a valid start bit begins again. If RxD is still low, a valid start bit is assumed. The receiver then continues to sample the input at one– ...

... Philips Semiconductors Enhanced octal universal asynchronous receiver/transmitter (Octal UART) Note: The transmitter may also control the “RTSN” pin. When un- der transmitter control the meaning is completely changed. The meaning is the transmission has ended. This signal is usually used to switch (turnaround) a bi–directional driver from transmit to re- ceive ...

... Philips Semiconductors Enhanced octal universal asynchronous receiver/transmitter (Octal UART) receiver indicating that the receiver is ready to receive data also active low and is, thus, called RTSN. RTSN is on pin MPO. A receiver’s RTS output will usually be connected to the CTS input of the associated transmitter. Therefore, one could say that RTS and ...

... Philips Semiconductors Enhanced octal universal asynchronous receiver/transmitter (Octal UART) REGISTERS The operation of the Octal UART is programmed by writing control words into the appropriate registers. Operational feedback is provided via status registers which can be read by the CPU. Addressing of the registers is described in Table 1. The bit formats of the Octal UART registers are depicted in Table 2. ...
