reset output. Output. Active High. When
resout is asserted, it indicates that the
IA186EB is being reset. The resout signal will
remain active (high) as long as resin_n
remains active (low).
Receive (rx) data, Serial Port 0. Input/Output.
This pin is the serial data input for Serial Port 0.
During synchronous serial communications,
rxd0 is bidirectional and functions an output for
data transmission (txd0 becomes the clock).
Receive (rx) data, Serial Port 1. Input/Output.
This pin is the serial data input for Serial Port 1.
During synchronous serial communications,
rxd1 is bidirectional and functions an output for
data transmission (txd1 becomes the clock).
statusN (N = 0–2). Output. During a bus cycle
the status (i.e., type) of cycle is encoded on
these lines as follows:

serial interrupt, Serial Port 1. Output. Active
High. When sint1 is asserted (high), it
indicates that Serial Port 1 requires service.
timer 0 input. Input. Depending on the Timer
Mode programmed for Timer 0, this input is
used either as clock input or a control signal.
timer 0 output. Output. Depending on the
Timer Mode programmed for Timer 0, this
output can provide a single clock or a
continuous waveform.
timer 1 input. Input. Depending on the Timer
Mode programmed for Timer 1, this input is
used either as clock input or a control signal.
