Daisy Chain Input [1:0].
These pins are used only in MIO mode.
SystemBase’s MIO Bus can be expanded up to 32 serial ports by 8 ports.
The ports are managed with Daisy Chain in order for 8 ports’ install
information to be automatically recognized. These pins are the input of
Daisy Chain.
Daisy Chain Output [1:0].
These pins are used only in MIO mode.
SystemBase’s MIO Bus can be expanded up to 32 serial ports by 8 ports.
The ports are managed with Daisy Chain in order for 8 ports’ install
information to be automatically recognized. These pins are the output of
Daisy Chain.
These pin are dual mode pins. After power is supplied to the chip,
the pin is set to input mode for a while and receive OSC[1:0] input.
After that, the pins are set to output mode and outputs nPNEN[1:0]
values. The pins are only used in MIO mode.
In input mode, OSC[1:0] values mean
In output mode, nPNEN[1:0] values mean
These pin are dual mode pins. After power is supplied to the chip,
the pin is set to input mode for a while and receive INTF[1:0] input.
After that, the pins are set to output mode and outputs nPNEN[3:2]
values. The pins are only used in MIO mode.
In input mode, OSC[1:0] values mean
In output mode, nPNEN[1:0] values mean
OSC[1:0] = 00b : Use 1.8432MHz UART Clock.
OSC[1:0] = 01b : Use 3.6864MHz UART Clock.
OSC[1:0] = 10b : Use 7.3728MHz UART Clock.
OSC[1:0] = 11b : Use 14.7456MHz UART Clock.
nPNEN[3:0] = 0000b : No serial port on MIO Bus.
nPNEN[3:0] = 0001b : 8 serial ports used on MIO Bus.
nPNEN[3:0] = 0011b : 16 serial ports used on MIO Bus.
nPNEN[3:0] = 0111b : 24 serial ports used on MIO Bus.
nPNEN[3:0] = 1111b : 32 serial ports used on MIO Bus.
INTF[1:0] = 00b : Use RS232 Interface
INTF[1:0] = 01b : Use RS422 Interface
INTF[1:0] = 10b : Use RS485 Interface
INTF[1:0] = 11b : Use Unknown Interface
