3.4.17 Safety Connector

A 12x2 standard 0.1” spaced header- TSW-112-07-S-D is included as a safety signal connector. The safety connector includes signals connected to the MCU. The 24 pins include MCU_I2C0, MCI_I2C1, MCU_UART1, MCU_SPI0 and MCU_SPI1 signals. This provides eighteen signals that can be used as either the specified interface or as MCU_GPIOs. In addition the CONN_MCU_RESETz, CONN_MCU_PORz, MCU_RESETSTATz and MCU_SAFETY_ERRORn signals are supported with the connector.
