Instructions
The Boundary Scan Register statuses during execution each
instruction vary according to the instruction code and SRAM
operation mode.
There are two statuses:
Pad
Internal : Contents of the SRAM internal output “SRAM
: Contents of the output pin (QDR Pad) are captured
in the “CAPTURE Register” in the Boundary Scan
Register.
Output” are captured in the “CAPTURE Register”
in the Boundary Scan Register.
