IEEE 1149.1 Test Access Port (JTAG)
31.3.1.3 Bypass Register
The bypass register is a single-bit shift register path from TDI to TDO when the BYPASS,
CLAMP, or HIGHZ instructions are selected. After entry into the Capture-DR state, the single-bit
shift register is set to a logic 0. Therefore, the first bit shifted out after selecting the bypass register
is always a logic 0.
31.3.1.4 TEST_CTRL Register
The TEST_CTRL register is a 1-bit shift register path from TDI to TDO when the
ENABLE_TEST_CTRL instruction is selected. The TEST_CTRL transfers its value to a parallel
hold register on the rising edge of TCLK when the TAP state machine is in the Update-DR state.
The DSE bit selects the drive strength used in JTAG mode.
