Boundary Scan Register (BSR)
The BSR is a shift register that provides access to all the digital I/O pins. The BSR is used to apply
and read test patterns to/from the board. Each pin is associated with a scan cell in the BSR register.
Bidirectional pins or tristatable pins require more than one position in the register. Table 35 shows
the BSR scan cells and their functions. Data into the BSR is shifted in LSB first.

HIZ3
HIZ3 controls the RPOS3, RNEG3 and RCLK3 pins. Setting HIZ3 to “0”
enables output on the pins. Setting HIZ3 to “1” tristates the pins.
