10.12.2 Displaying a specified register
1. Send command WRITE PDB REGISTER and GO (no EX).
(ODEC selects PDB as destination for serial data.)
2. ACK
3. Send the 32-bit opcode: "MOVE reg,x:OGDB"
(After 32 bits have been received, the PDB register drives the PDB. ODEC releases the chip
from the "halt" state and the contents of the register specified in the instruction are loaded in
the GDB REGISTER. The signal that marks the end of the instruction returns the chip to the
"halt" state and an acknowledge is issued to the command controller.)
4. ACK
5. Send command READ GDB REGISTER
(ODEC selects GDB as source for serial data and an acknowledge is issued to the command
controller.)
6. ACK
7. CLK
10.12.3 Displaying X memory area starting from address xxxx
This command uses Rn to minimize serial traffic.
1. Send command WRITE PDB REGISTER and GO (no EX).
(ODEC selects PDB as destination for serial data.)
2. ACK
3. Send the 32-bit opcode: "MOVE R0,x:OGDB"
(After 32 bits have been received the PDB register drives the PDB. ODEC releases the chip
from the "halt" state and the contents of R0 are loaded in the GDB REGISTER. The signal that
marks the end of the instruction returns the chip to the "halt" state and an acknowledge is is-
sued to the command controller.)
