AFE4405: AFE4405 "I2C_SPI_SEL" and "CONTROL1" pin current flow

Part Number: AFE4405

In the AFE4405 datasheet, there is two control pin(I2C_SPI_SEL, CONTROL1). 

Datasheet doesn't describe electrical specification how much current flow in when those two pin has High state. 

Only clue depiction is full datasheet pdf page 7 like below,

"(8) This current depends on the percentage of time for which the I2C_CLK is low; and scales with FIFO_NPHASE and PRF. This extra component of current is negligible when operating in the SPI interface mode. However, note that pulling the I2C_SPI_SEL pin high causes an extra current to flow through the pulldown resistor on the I2C_SPI_SEL pin"

Could I know how can I estimate current consumption when apply High voltage?
