GPIO_C1
Alternate Function 1 (GPIO)
GPIO_1 on Port C.
SPI1_REQ
Alternate Function 2
External data transfer rate control for SPI1
.
UART_RXD
/GPIO_C2/TIM_0_I
UART_RXD
Normal mode
UART receive data serial (input signal).
GPIO_C2
Alternate Function 1 (GPIO)
GPIO_2 on Port C.
TIM_0_I
Alternate Function 2
Input signal to timer 0.
UART_RTS
/GPIO_C3/TIM_1_I
UART_RTS
Normal mode
UART ready to send (RTS) input signal, when asserted, indicates
that the remote device is ready to accept new data and that the
MC72000 can transmit when it has data to send.
GPIO_C3
Alternate Function 1 (GPIO)
GPIO_3 on Port C.
TIM_1_I
Alternate Function 2
Input signal to timer 1.
SPI1_SS
/GPIO_C4/SYSCLK
SPI1_SS
Normal mode
Slave Select: This bi-directional signal is an output in master mode
and an input in slave mode.
GPIO_C4
Alternate Function 1 (GPIO)
GPIO_4 on Port C.
SYSCLK
Alternate Function 2
System clock used by the entire ARM7 platform and all peripherals
attached to the IP and AHB bus. Some of the peripherals (for
example, UART) will also use this clock signal to generate their own
module clock.
SPI1_SCK
/GPIO_C5/SH_STROBE
SPI1_SCK
Normal mode
This bi-directional signal is the SPI clock output in master mode. In
slave mode, SPI1_SCK is an input clock signal to the SPI.
GPIO_C5
Alternate Function 1 (GPIO)
GPIO_5 on Port C.
SH_STROB
E
Alternate Function 2
Indicates data is valid on the external bus when show cycle is used.
SPI1_MISO
/GPIO_C6/ABORT
SPI1_MISO
Normal mode
Master In Slave Out (MISO): In master mode, this bi-directional
signal is the RXD input signal. In slave mode, MISO is the TXD
output signal.
GPIO_C6
Alternate Function 1 (GPIO)
GPIO_6 on Port C.
ABORT
Alternate Function 2
Indicates the current memory access cannot be completed.
SPI1_MOSI
/GPIO_C7/REFCLK
SPI1_MOSI
Normal mode
Master Out Slave In (MOSI): In master mode, this bi-directional
signal is the TXD output signal. In slave mode, MOSI is the RXD
input signal.
