2.4.4 Different Pin definition setting

• SLED, CCFT, DISPLAY, SPKCTL, SQWO and GPIOC2 pins are all internal pull high 50K

ohms. The blank part of following table means keeping the original pin definition.

• When SLED default is pulled high, the chip will be in normal mode.• When SLED is pulled low by 4.7K resistor, the chip will be in test mode.• When GPIOC2 pull low, the PCI ports are 0078/007A and offset 0F6h D15 will be set, otherwise,

0178/017A.
