module into the power-on reset state.
0: Puts the PC trace unit of UBC into the reset state
1: Releases reset in the PC trace unit of UBC
This bit is not supported on 32 Kbyte versions
(SH71251A, SH71241A) and 16 Kbyte versions
(SH71250A, SH71240A).
These bits are always read as 0. The write value should
always be 0.
