Table 2.5. Chips installation and interrupt sources
When 2 default chips (#1 and #2) are installed on ACL-8454,
/
COUT6 is internal but COUT12 can be used as external interrupt
source. ECK10 is still used as digital input pin. If user installs the
chip #3 by yourself, the interrupt sources are in the same
configuration as condition 1.
When all 4 chips are installed, / COUT6 , COUT12 are internal
interrupt sources, only ECLK10 can be used as external. If user
installs the chip #4 by yourself, the interrupt sources are the same
configuration as condition 2.
2.13 Digital Input and Output
To program digital I/O operation is fairly straight forward. The digital
input operation is just to read data from the corresponding registe rs,
and the digital output operation is to write data to the corresponding
registers. The digital I/O registers‘ format are shown in section 3.11.
It is not necessary to set any jumper for digital I/O.
The ACL-8454 provides 16 digital input and 8 digital output channels
through the connector CN1. The digital I/O signals are fully TTL/DTL
compatible.
