5.2.3 Digital I/O
The RCM3600 was designed to interface with other systems, and so there are no drivers
written specifically for the I/O. The general Dynamic C read and write functions allow
you to customize the parallel I/O to meet your specific needs. For example, use
to set all the Port E bits as inputs, or use
to set all the Port E bits as outputs.
When using the auxiliary I/O bus on the Rabbit 3000 chip, add the line
to the beginning of any programs using the auxiliary I/O bus.

void timedAlert(unsigned long timeout);
void digInAlert(int dataport, int portbit,
This function is used to poll the real-time clock until the specified timeout occurs. The RCM3600 will
operate in a low-power mode with a clock speed of 2.048 kHz until the timeout occurs. Once the timeout
has ended, the RCM3600 will resume operating at 22.1 MHz. The analog device oscillator will be dis-
abled until the timeout occurs and will then be enabled as well.
timeout is the length of the timeout in seconds
None.
This function is used to poll a digital input for a certain value or until the specified timeout occurs. The
RCM3600 will operate in a low-power mode with a clock speed of 2.048 kHz until the correct bit is
received or the timeout occurs. Once this happens, the RCM3600 will resume operating at 22.1 MHz.
The analog device oscillator will be disabled until the timeout occurs and will then be enabled as well.
dataport is the input port data register corresponding to the channel to poll (e.g., PADR)
portbit is the input port bit to poll
value is the input value (0 or 1) to receive
timeout is the length of the timeout in seconds if an input value is not received on the specified chan-
nel; enter 0 for no timeout
None.
