All MC68EN302 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. Fifty bits in the bound-
ary scan register define the output enable signal for associated groups of bidirectional and
three-stateable output pins. The control bits and their bit positions are listed in Table 7-1.
The boundary scan bit definitions are listed in Table 7-2.
The first column in the table defines the bit’s ordinal position in the boundary scan register.
The shift register cell nearest TDO (i.e., first to be shifted out) is defined as bit 0; the last bit
to be shifted out is 162.
The second column references one of the seven MC68EN302 cell types depicted in Figure
7-3 through Figure 7-9, which describe the cell structure for each type.
The third column lists the pin name for all pin-related cells or defines the name of bidirec-
tional control register bits.
The fourth column lists the pin type for convenience, where Output indicates a three-state-
able output pin, I/O indicates a bidirectional pin and Input represents an input.
The last column indicates the associated boundary scan register control bit for bidirectional
and output pins.
Bidirectional pins include a single scan cell for data (bicell) as depicted in Figure 7-6. These
bits are controlled by the cell shown in Figure 7-5. The value of the control bit determines
whether the bidirectional pin is an input or an output. One or more bidirectional data cells
