Section 28 Power-Down Modes
28.2.14 Retention On-Chip RAM Trimming Register (DSRTR)
DSRTR is an 8-bit readable/writable register used to trim the standby current for the on-chip RAM
for data retention in deep standby mode. Only byte access is valid.
To retain data on the on-chip RAM for data retention in deep standby mode, be sure to write H'09
to this register before making a transition to deep standby mode.
This register is initialized after the assertion of the RES pin or exit from deep standby mode.
Note: When writing to this register, see section 28.4, Usage Notes.
