Note: 1. The test pins are as follows: TESTI1, TESTI2, TESTI3, TESTI4
2. The pulldown pins are not included.
3. The pulldown pins are as follows (Typ 50 kΩ):
TESTI1, TESTI2, TESTI3, TESTI4, SDINA, SDIND1, SDIND2, SDIN1, SDIN2, OPCL,
CS, JX, SI, CTRL0, CTRL1
Note: Regarding the input/output levels in the text, the low level is represented as "L" or 0, and the high level as "H" or 1.
In principle, "0" and "1" are used for the bus (serial/parallel), such as registers.
(3) Current consumption
(AVDD = AVB, DVB, DVDD = 5.0 V±5%, Ta = 25°C; master clock (XTI) = 22.5792MHz = 512 fs [fs = 44.1kHz]; when
operating for DAC 4 channel with 1 kHz sinusoidal wave full-scale input to each of ADC 2 ch analog input pins)

Note: 1. Varies slightly according to the frequency used and contents of the DSP program.
Note: 2. This is a reference value in case of using the crystal oscillator.
But, varies slightly according to the types of crystal oscillators.
