Description
Bus select. Intel or Motorola bus select.
When 16/68 pin is at logic 1 or left unconnected (internally pulled-up) the
device will operate in Intel bus (16 mode) type of interface.
When 16/68 pin is at logic 0, the device will operate in Motorola bus (68 mode)
type of interface.
Address 0 select bit. Internal register address selection.
Address 1 select bit. Internal register address selection.
Address 2 select bit. Internal register address selection.
Carrier Detect (active LOW). A logic 0 on this pin indicates that a carrier has
been detected by the modem. Status can be tested by reading MSR[7].
Chip Select (active LOW). In 16 mode or 68 mode, this input is chip select for
the UART.
Clear to Send (active LOW). A logic 0 on the CTS pin indicates the modem
or data set is ready to accept transmit data from the SC16C850. Status can be
tested by reading MSR[4].
Data Set Ready (active LOW). A logic 0 on this pin indicates the modem or
data set is powered-on and is ready for data exchange with the UART. Status
can be tested by reading MSR[5].
Data Terminal Ready (active LOW). A logic 0 on this pin indicates that the
SC16C850 is powered-on and ready. This pin can be controlled via the
modem control register. Writing a logic 1 to MCR[0] will set the DTR output to
logic 0, enabling the modem. This pin will be a logic 1 after writing a logic 0 to
MCR[0], or after a reset.
2.5 to 3.3 V UART with 128-byte FIFOs and IrDA encoder/decoder
