Note 1) The pull-down pins and XTI pin are not included.
Note 2) The pull-down pins are: CS , SDIN4/JX2, SDIN3/JX1, SDIN2, SDIN1/JX0, TESTI
Note:
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.
(3) Current Consumption
(AVDD=DVDD=3.0V~3.6V, Ta=25°C; master clock (XTI)=18.432MHz=384fs[fs=48kHz];
PLL is in active mode. )

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