3) INIT_RESET ="L"(reference)
Note 1) Varies slightly different according to the system frequency and contents of the DSP program.
Note 2) Max value is “Double Speed” mode.
Note 3) This is a reference value when using the crystal oscillator. Because most of the power current at the initial reset state is in
Regarding the input/output levels in the text, the low level will be represented as "L" or 0, and the high level as "H" or 1. In
principle, "0" and "1" will be used to represent the bus (serial/parallel) such as registers.

the oscillator section, the value may vary slightly according to the type of crystal oscillators and external circuits.
This is a reference value only.
