Chip select not input: this input is low active and requires CMOS logic
levels. The serial data transfer between L99H01 and microcontroller is
enabled by pulling the input CSN to low-level. This input has a pull-up
current.
Serial clock input: this input controls the internal shift register of the
SPI and requires CMOS logic levels.This input has a pull-down
current.
Serial data in: the input requires CMOS logic levels and receives serial
data from the microcontroller. The data is an 8-bit control word and the
most significant bit (MSB, bit 7) is transferred first. This input has a
pull-down current.
Serial data out: the diagnosis data is available via the SPI and this
tristate-output. The output remains in tristate, if the chip is not selected
by the input CSN (CSN = high).
Not connected.
Current sense amplifier output: V
Current sense amplifier input: positive input 1, multiplexible.
Current sense amplifier input: negative input 1, multiplexible.
Current sense amplifier input: positive input 2, multiplexible.
Current sense amplifier input: negative input 2, multiplexible.
