Pin 6 (UART_RI) is active low. It is normally 3.0v. When a remote device initiates a connection, this
pin goes low. This means that when this pin is converted to RS232 voltage levels it will have the
correct voltage level for assertion.
Pin 8 (UART_DCD) is active low. It is normally 3.0v. When a connection is live this pin is low. This
means that when this pin is converted to RS232 voltage levels it will have the correct voltage level for
assertion.
Pin 10 (UART_DSR) is an input, with active low logic. It should be connected to the DTR output of the
host. When the BISM II PA Module is in high speed mode (See definition for S Register 507), this pin
should be asserted by the host to ensure that the connection is maintained. A deassertion is taken to
mean that the connection should be dropped, or an online command mode is being requested.
Pin 27 (VCC_3V0 monitor) may only be used for monitoring purposes.
current source.
The GPIO pins can be accessed using S Registers 621 to 628.
GPIO3 is also used for DTR output (active low). See S Register 552 & 553.
Analogue 0 and 1 should not exceed 1.8v and S Registers 701 and 702 are used to access them.
