PRODUCTION DATA
Table 9-7 lists the I/O buffer types and descriptions. Table 9-8 lists the pin to I/O buffer mapping for cross-referencing a pin’s particular I/O structure. The following sections show a simplified version of the architecture of each I/O buffer type.
BUFFER TYPE | DESCRIPTION |
---|---|
IOBUF_GPIOHSSWD | General Purpose High-Speed I/O |
IOBUF_GPIOHSSPI | General Purpose High-Speed I/O |
IOBUF_GPIOLS | General Purpose Low-Speed I/O |
IOBUF_GPIOLSI2C | General Purpose Low-Speed I/O with I2C deglitch time |
IOBUF_I2C | I2C Compliant Clock/Data Buffers |
IOBUF_OD | Open-Drain Output |
IOBUF_UTX | Push-Pull output buffer for UART |
IOBUF_URX | Input buffer for UART |
IOBUF_PORT | Input buffer between 1st/2nd stage Port Data Mux |
I/O GROUP/PIN | BUFFER TYPE | SUPPLY CONNECTION (DEFAULT FIRST) |
