(Note)

*1 In case of using TCXO, set TCXO_EN=0b1. Please make sure only one of the register TCXO_EN,

XTAL_EN is set to 0b1.

*2 For ML7344Jy, the initial value of the register TCXO_EN is 0b1. In case of using ML7344JC, the register

XTAL_EN([CLK_SET2: B0 0x03(4)])=0b1 must be programmed first.

*3 For ML7344Cy, the initial value of the register XTAL_EN is 0b1. In case of using ML7344CT, the

*4 Please refer to [EXTCLK_CTR: B0 0x52] register.

*5 Please refer to [GPIO0_CTRL: B0 0x4E] register

*6 Please refer to [GPIO1_CTRL: B0 0x4F] register

*7 Please refer to [GPIO2_CTRL: B0 0x50] register

*8 Please refer to [GPIO3_CTRL: B0 0x51] register
