26.3.1
Instruction Register (SDIR)
SDIR is a 32-bit register. JTAG instructions can be transferred to SDIR by serial input from the
ETDI pin. SDIR can be initialized when the
ETRST
pin is low or the TAP controller is in the
Test-Logic-Reset state, but is not initialized by a reset or in standby mode.
Only 4-bit instructions can be transferred to SDIR. If an instruction exceeding 4 bits is input, the
last 4 bits of the serial data will be stored in SDIR.
