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

An I2C-bus slave transmitter interface is included to provide the possibilities for a host to send control data and/or read

monitoring information. For details of the interface protocol and timing on the I2C-bus see “The I2C-bus and how to use

it”; 12NC number 9398 393 40011.

DESCRIPTION(1)

output data Port 5 to Port 0

mode control Port 5 to Port 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;

default: ERF = 1, mode control = 111111 (default = default value after a hardware reset).
