8.3 BOUNDARY SCAN REGISTER
The QUICC scan chain implementation has a 196-bit boundary scan register. This register
contains bits for all device signal and clock pins and associated control signals. The XTAL,
and XFC pins are associated with analog signals and are not included in the boundary scan
register.
All QUICC bidirectional pins have a single register bit in the boundary scan register for pin
data and are controlled by an associated control bit in this register. Twenty-five bits in the
boundary scan register define the output enable signal for associated groups of bidirectional
and three-stateable pins. The control bits and their bit positions are listed in Table 8-1.
