DSCNT is an 8-bit readable/writable register that selects the clock used to count the oscillation
settling time when the system returns from deep standby mode. DSCNT is initialized to H'00 by a
power-on reset or in deep standby mode but retains its previous value by a manual reset or in
software standby mode. Only byte access is valid.
Since the frequency control register for the CPG (FRQCR) is initialized in deep standby mode, the
frequency of the peripheral clock (Pφ) specified by the CKS[2:0] bits in DSCNT is determined by
the FRQCR's initial value.
Notes: 1. Do not use this setting.

These bits are always read as 0. The write value
should always be 0.
Clock Select
Selects the clock used to count the oscillation settling
time from among eight types clocks derived by
dividing the peripheral clock (Pφ).
The oscillation settling time is calculated as follows:
Oscillation settling time = 1/Pφ × Division ratio
specified by CKS[2:0] × 255 [μs]
The following are the oscillation settling times when
the peripheral clock (Pφ) is running at 5, 10, and 15
MHz.
