AD7712 to 68HC11 Interface
Figure 19 shows an interface between the AD7712 and the
68HC11 microcontroller. The AD7712 is configured for its
external clocking mode, while the SPI port is used on the
68HC11, which is in its single-chip mode. The
DRDY line
from the AD7712 is connected to the Port PC2 input of the
68HC11 so the
DRDY line is polled by the 68HC11. The
DRDY line can be connected to the IRQ input of the 68HC11,
if an interrupt driven system is preferred. The 68HC11 MOSI
and MISO lines should be configured for wired-OR operation.
Depending on the interface configuration, it may be necessary
to provide bidirectional buffers between the 68HC11 MOSI
and MISO lines.
The 68HC11 is configured in the master mode with its CPOL
bit set to a Logic 0 and its CPHA bit set to a Logic 1. With a
10 MHz master clock on the AD7712, the interface will operate
with all four serial clock rates of the 68HC11.
