• Manufacturer Part Number: HI-6120
• Description: MIL-STD-1553 Remote Terminal ICs
• Manufacturer: HOLTIC [Holt Integrated Circuits]

Using a different SPI op code, the host can sequentially read the entire Descriptor Table.

The host may repeat this sequence until the entire Descriptor Table is read. The repeating read process is not shown,
but the sequence could end like this, continuing beyond the table boundary…

==========================================
op code writes memory address pointer (MAP)
decremented table start addr 0x0200 - 1 written to MAP
op code pre-increment MAP then read addressed location
data from 0x0200 (SCK continues afterward)
data from 0x0201 (SCK continues afterward)
data from 0x0202 (SCK continues afterward)
data from 0x0203 (SCK stops and /CS is negated)
op code pre-increment MAP then read addressed location
data from 0x0204 (SCK continues afterward)
data from 0x0205 (SCK continues afterward)
data from 0x0206 (SCK continues afterward)
data from 0x0207 (SCK stops and /CS is negated)
op code pre-increment MAP then read addressed location
data from 0x0208 (SCK continues afterward)
data from 0x0209 (SCK continues afterward)
data from 0x020A (SCK continues afterward)
data from 0x020B (SCK stops and /CS is negated)
op code pre-increment MAP then read addressed location
