6 / 23 page SERCON816 6/23 RxD 14 I Receive data for the serial interface. RxC 12 O Receive clock for the serial interface. Output of the internally generated receive clock. RECACTN 26 O Receive active, active low. Indicates that the serial receiver is receiving a telegram. TxD1 16 O Transmit data. The pin can be switched to a high impedance state. TxD6-2 22,21,20, 18,17 O Transmit data or output port. The pins either output the serial data or can be used as parallel output ports. When they output transmit data, each pin can be switched to a high impedance state individually. TxC 13 O Transmit clock for the serial interface. Output for the internally generated transmit clock. IDLE 25 O Transmitter active, active low. When transmitting own data IDLE is 0. DMAREQT 39 O DMA request transmit, active high: becomes active when data can be written to the transmit FIFO. DMAREQT becomes inactive again at the beginning of the last write access to the transmit FIFO. DMAACKTN 41 I DMA acknowledge transmit, active low: when DMAACKTN is 0, the transmit FIFO is written to when there is a bus write access independent of the levels on A6-1 and the chip select signals. ADMUX 96 I Address data bus: when ADMUX is 0 A15-0 are the address inputs, when ADMUX is 1 A15-0 are the outputs of the address latch. BUSMODE0, BUSMODE1 97,98 I Bus mode: BUSMODE0 = 0 turns on the Intel bus interface (RDN = read, WRN = write), BUSMODE0 = 1 selects the Motorola interface (RDN = data strobe, WRN = read/write). BUSMODE1 selects the 0-active data strobe (BUSMODE1 = 0) or the 1-active data strobe (BUSMODE1 = 1). BUSWIDTH 99 I Bus width: selects the 8-bit- (0) or the 16-bit-wide interface (1). BYTEDIR 100 I Byte address sequence: when BYTEDIR is 0, A0 = 0 addresses the lower 8 bits of a word (low byte first), when BYTEDIR is 1, the upper 8 bits of a word are addressed (high byte first). INT0, INT1 44,43 O Interrupts, active low or active high. Interrupt sources and signal polarity are programmable. SBAUD16 28 I Baud rate and SERCON410B compatible mode: SBAUD and SBAUD16 selects the baud rate for the serial interface. If SBAUD16 is ‘1’ the SERCON410B compatible mode is selected. SBAUD 29 I Baud rate. Can be overwritten by the microprocessor. RxD 14 I Receive data for the serial interface. RxC 12 O Receive clock for the serial interface. Output of the internally generated receive clock. RECACTN 26 O Receive active, active low. Indicates that the serial receiver is receiving a telegram. TxD1 16 O Transmit data. The pin can be switched to a high impedance state. TxD6-2 22,21,20, 18,17 O Transmit data or output port. The pins either output the serial data or can be used as parallel output ports. When they output transmit data, each pin can be switched to a high impedance state individually. TxC 13 O Transmit clock for the serial interface. Output for the internally generated transmit clock. IDLE 25 O Transmitter active, active low. When transmitting own data IDLE is 0. TM0, TM1 30,31 I Turn on test generator: TM0 = 0 switches TxD1-6 to contiuous signal light, TM1 = 0 switch-over to zero bit stream. The processor can overwrite the level of TM1-0. Select repeater mode at reset time: TM1=0 and TM2=0 repeater off, all other repeater on. Table 1. SERCON816 I/O Port Function Summary (continued) Signal(s) Pin(s) IO Function |
