... The VNC1L bootloader uses the UART interface to load new firmware into the Vinculum Flash memory. To enable the bootloader, the PROG# pin must be driven low and VNC1L must then be reset by driving the RESET# pin low then high. Run mode can be enabled by driving the PROG# pin high and then resetting VNC1L by driving the RESET# pin low then high ...

... There are three firmware interface options for the command monitor on the combined control and data interface. The command monitor interface options are UART, FIFO or SPI. The mode of operation is selected using VNC1L pins 46 and 47.The pin connections used to select the mode of the interface are shown in Table 5.1: Pin No ...

... TXDEN will be set high one bit-time before data is transmitted and return low one bit time after the last bit of a data frame has been transmitted. The ring indicator pin, RI#, is used to wake up VNC1L from suspend mode. The suspend mode can be entered using a firmware monitor command. ...

... The encoding of the setup bits is shown in Table 5.3. A single data byte is transmitted in each SPI transaction, with the most significant bit transmitted first. After each transaction VNC1L returns a single status bit. This indicates if a Data Write was successful or a Data Read was valid. ...

... The Start and Setup sequence is sent to VNC1L by the SPI master, see Figure 5.4. The VNC1L clocks out data from its Transmit Buffer on subsequent rising edge clock cycles provided by the SPI master. This is followed by a status bit generated by VNC1L. The Data Read status bit is defined in Table 5.6. ...

... VNC1L, see Figure 5.5. This is followed by the SPI master transmitting each bit of the data to be written to VNC1L. The VNC1L then responds with a status bit on SDO on the rising edge of the next clock cycle. The SPI master must read the status bit at the end of each write transaction to determine if the data was written successfully to VNC1L Receive Buffer ...

The VNC1L clocks out its status byte on subsequent rising edge clock cycles from the SPI master. This is followed by a status bit generated by VNC1L (also on the SDO) which will always be zero (indicating new data) ...

... Block Diagram - VNC1L Programming Via USB Interface VNC1L can be programmed from a PC USB port using an FTDI USB-serial converter such as the FT232R. This is the fastest way to reprogram VNC1L Flash memory as data can be transferred to VNC1L 1MBaud. The required connections between VNC1L and an FT232R device for controlling the PROG# and RESET# pins is shown in Figure 7 ...
