Mode of operation
Table 2 Mode of operation for boundary scan test
Note
1. The safest way to deactivate the Boundary Scan Test (BST) circuitry is to set TRST to logic 0.
Control, monitoring and extension port interface

it” ; 12NC number 9398 393 40011.
Table 3 Slave address
Note
1. When X = 1 = read; when X = 0 = write.
Table 4 Write (R/W = 0)
Notes
1. Output data bits for port 5 to port 0; mode control bits for Port 5 to Port 0 (1 = input, 0 = output).
2. Sending the 2nd byte will force the IC to reset.
3. When ERF = 1 the error flag is set for uncorrectable blocks; when ERF = 0 the error flag is always left unmodified;
