APEX 20KC Programmable Logic Device Data Sheet

The APEX 20KC device instruction register length is 10 bits. The

APEX 20KC device USERCODE register length is 32 bits. Tables 14 and 15

show the boundary-scan register length and device IDCODE information

for APEX 20KC devices.

Notes to Table 15:

(1)

The most significant bit (MSB) is on the left.

(2)

The IDCODE’s least significant bit (LSB) is always 1.

Figure 30 shows the timing requirements for the JTAG signals.
