• Manufacturer: Holt Integrated Circuits

FUNCTIONAL DESCRIPTION
CONTROL WORD REGISTER
The HI-8582 contains a 16-bit control register which is used to
configure the device. The control register bits CR0 - CR15 are
loaded from BD00 - BD15 when
register contents are output on the databus when SEL=1 and
is pulsed low. Each bit of the control register has the following
function:

STATUS REGISTER
The HI-8582 contains a 9-bit status
interrogated to determine the status of the ARINC receivers, data
FIFOs and transmitter. The contents of the status register are output
on BD00 - BD08 when the
bits are output as zeros. The following table defines the status
register bits.
