BYPASS

1. Places Qs in high-Z in order to sample all input data, regardless of other SRAM inputs.
2. TDI is sampled as an input to the first ID register to allow for the serial shift of the external TDI data.
3. BYPASS register is initiated to VSS when BYPASS instruction is invoked. The BYPASS register also holds the last serially loaded
TDI when exiting the shift-DR state.
4. SAMPLE instruction does not place DQs in high-Z.
5. This instruction is reserved. Invoking this instruction will cause improper SRAM functionality.
6. This EXTEST is not IEEE 1149.1-compliant. By default, it places Q in high-Z. If the internal register on the scan chain is set high,
Q will be updated with information loaded via a previous SAMPLE instruction. The actual transfer occurs during the update IR
state after EXTEST is loaded. The value of the internal register can be changed during SAMPLE and EXTEST only.
