register bit 1, the state of DTR pin can be controlled as below. Writing to
IOState bit 5 will not have any effect on this pin.
Rev. 06 — 13 May 2008
logic 0 = divide-by-1 clock input
logic 1 = divide-by-4 clock input
logic 0 = normal UART mode
logic 1 = IrDA mode
logic 0 = disable Xon Any function
logic 1 = enable Xon Any function
logic 0 = normal operating mode
logic 1 = enable local Loopback mode (internal). In this mode the
MCR[1:0] signals are looped back into MSR[4:5] and the TX output is
looped back to the RX input internally.
logic 0 = disable the TCR and TLR register.
logic 1 = enable the TCR and TLR register.
logic 0 = force RTS output to inactive (HIGH)
logic 1 = force RTS output to active (LOW). In Loopback mode,
controls MSR[4]. If Auto RTS is enabled, the RTS output is controlled
by hardware flow control.
logic 0 = Force DTR output to inactive (HIGH)
logic 1 = Force DTR output to active (LOW)
