ZHCSNJ7A April 2021 – February 2023 TDES954
PRODUCTION DATA
In addition to the dedicated LOCK and PASS output pins, the TDES954 supports seven pins, GPIO0 through GPIO6, which can be monitored, configured, and controlled through I2C in registers 0x0E - 0x16. GPIO3 programmable I/O pin is an active-low open drain and is shared with INTB. The current status of all GPIO can be readback from register 0x0E. Each GPIO is programmable for multiple uses options through the GPIOx_PIN_CTL registers 0x10 - 0x16.
