22.3.2
The status register (SDSR) is a 16-bit register that can be read and written to by the CPU. The
SDSR value can be output from TDO, but serial data cannot be written to SDSR via TDI. The
SDTRF bit is output by means of a one-bit shift. In a two-bit shift, the SDTRF bit is output first,
followed by a reserved bit.
SDSR is initialized by TRST signal input, but is not initialized in software standby mode.

Serial Data Transfer Control Flag
Indicates whether H-UDI registers can be accessed by
the CPU. The SDTRF bit is initialized by the TRST
signal, but is not initialized by a reset or in software
standby mode.
