SCL and SDA Pin Description
Pull-up Enable
The pull-up enable for SCL and SDA is activated for AP386X, meaning that AP386X always has pull-up SCL
and SDA to VDD3V. During reset, SCL and SDA are as input pin. Moreover, if the pin connecting to the system
is floating, the internal pull-up will tie the pin to VDD3V (10k). After AP386X is reset, SCL and SDA are
input until its corresponding register is configured.
Mode Selection
SCL and SDA can be used in I2C and SPI mode. AP386X can enable I2C mode (SCL and SDA configured as
open drain pin) by register setting.
Wakeup
SCL and SDA can be used for wakeup input signals in different mode. While I2C mode is enabled, a START
protocol (SDA is low and SCL is high) on SCL and SDA is a wakeup signal to AP386X. While SPI mode is
enabled, an active low on the pin of SCL (serving as a slave select in SPI) is a wakeup signal to AP386X.
Moreover, a wakeup signal can be asserted by host from GPIO0.
INT/GPIO1
GPIO1 can be configured as open-drain or push-pull mode. Furthermore, GPIO1 pin has internal pull-up to
VDD3V (60k) or VDD18 (10k) based on different register definition.
