Description
Address and Data bus (bidirectional). These pins are the 8-bit multiplexed data bus and
address bus for transferring information to or from the controlling CPU. AD0 is the least
significant bit and is address A0 during the address cycle, and AD7 is the most significant bit
and is address A7 during the address cycle.
Carrier Detect (active LOW). A logic 0 on this pin indicates that a carrier has been detected
by the modem for that channel. Status can be tested by reading MSR[7].
Chip Select (active LOW). This pin enables the data transfers between the host and the
SC16C850V.
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 SC16C850V. 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 SC16C850V 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.
Pin configuration for HVQFN32
Single UART with 128-byte FIFOs, IrDA, and XScale VLIO bus interface
