Description
Trimming Data Register Write Enable
This register can be written to when the LOCKDW bit is 0
and this bit is 1.
[Setting condition]
[Clearing conditions]
Reserved
These bits are always read as 1.
Description
Trimming Data (FSEL = 1, 20 MHz)
The trimming data is loaded from the flash memory to this
register right after a reset.
The on-chip oscillator clock (FSEL = 1, 20 MHz) can be
trimmed by changing these bits.
The frequency of the on-chip oscillator clock changes
right after writing these bits. These bits are initialized to
H'00.
Changes in frequency are shown below (bit TRMD7 is a
sign bit).
(Min.) H'80
H'7F (Max.)
When writing 0 to the WRI bit while writing 1 to the
TRMDRWE bit while the PRWE bit is 1
Reset
When writing 0 to the WRI bit and writing 0 to the
TRMDRWE bit while the PRWE bit is 1
