SYMBOL
FUNCTION
TEST
Factory Use. Must be set to 0 for proper operation.
TEST
Factory Use. Must be set to 0 for proper operation.
CLK_INV
TCLKO Invert.
0 = TCLKO polarity is normal
1 = TCLKO polarity is inverted
R/W
Read/Write Select. This bit is used with the RAM bit to read or write the
RAM.
0 = Write to the RAM
1 = Read from the RAM
RAM
RAM Select. This bit should be set when repetitive pattern data is being
loaded into the RAM. See flowchart in Section 4 for a description of this
process.
0 = BERT state machine has control of the RAM
1 = Parallel port has read and write access to the RAM
COUNT
Select Bit for Registers Ah–Fh.
0 = Registers Ah–Fh refer to bit count registers.
1 = Registers Ah–Fh refer to error count registers.
SEED
Select Bit for Registers 5h–8h.
0 = Registers 5h–8h refer to tap select registers.
1 = Registers 5h–8h refer to preload seed registers.
PL8
Pattern Length Bit 8. Bit 8 of [8:0] End Address of Repetitive Pattern Data.
