UART Transmit Data Bus
UART mode: Each UART channel sends data on their respective output pin. Note that these pins default
to inputs at reset time and must be programmed via the PIO interface before being used as UART out-
puts.
uart_tx[0] Alternate function: PIO[5].
uart_tx[1] Alternate function: PIO[3].
UART Transmit Data Bus
UART mode: Data bus modem control signal pins for UART channel 0.
uart_cts_n[0] Alternate function: PIO[15].
uart_dsr_n[0] Alternate function: PIO[14].
uart_dtr_n[0] Alternate function: PIO[13].
uart_rts_n[0] Alternate function: PIO[12].
SPI Data Output
Serial mode: Output pin from RC32334 as an Input to a Serial Chip for the Serial data input stream.
In PCI satellite mode, acts as an Output pin from RC32334 that connects as an Input to a Serial Chip for
the Serial data input stream for loading PCI Configuration Registers in the RC32334 Reset Initialization
Vector PCI boot mode.
1st Alternate function: PIO[10]. Defaults to the output direction at reset time.
2nd Alternate function: pci_eeprom_mdo.
SPI Data Input
Serial mode: Input pin to RC32334 from the Output of a Serial Chip for the Serial data output stream.
In PCI satellite mode, acts as an Input pin from RC32334 that connects as an output to a Serial Chip for
the Serial data output stream for loading PCI Configuration Registers in the RC32334 Reset Initialization
Vector PCI boot mode.
Defaults to input direction at reset time.
1st Alternate function: PIO[7].
2nd Alternate function: pci_eeprom_mdi.
SPI Clock
Serial mode: Output pin for Serial Clock.
In PCI satellite mode, acts as an Output pin for Serial Clock for loading PCI Configuration Registers in the
RC323334 Reset Initialization Vector PCI boot mode.
1st Alternate function: PIO[9]. Defaults to the output direction at reset time.
2nd Alternate function: pci_eeprom_sk.
SPI Chip Select
Output pin selecting the serial protocol device as opposed to the PCI satellite mode EEPROM device.
Alternate function: PIO[8]. Defaults to the output direction at reset time.
CPU Non-Maskable Interrupt
Requires external pull-up.
This interrupt input is active low to the CPU.
CPU Master System Clock
Provides the basic system clock.
CPU Interrupt
Requires external pull-up.
These interrupt inputs are active low to the CPU.
CPU Cold Reset
This active-low signal is asserted to the RC32334 after
Reset initialization vectors for the RC32334 are latched by cold reset.
