Description
This pin has the following functions:
x CFIRQ: Interrupt request signal from CF card
This pin, when reset, becomes good for inputting
GPIOH6. To use as the CFIREQ pin, set bits [13:12] of
the GPIOH pin function register to “Function 1 other
than GPIO.”
x GPIOH6 I/O (Pin function right after reset)
x SDMCD#: Card detect input for SD card (Function 2 of
other than GPIO)
This pin has the following functions:
x CFSTSCHG#: Status change signal from CF card
(active low signal)
This pin, when reset, becomes good for inputting
GPIOH7. To use as the CFSTSCHG# pin, set bits
[15:14] of the GPIOH pin function register to “Function 1
other than GPIO.”
x GPIOH7 I/O (Pin function right after reset)
x SDMWP: Write protect input for SD card (Function 2
of other than GPIO)
This pin has the following functions:
x CFDEN#: Data bus enable signal for external buffer
of CF card (active low signal)
This pin, when reset, becomes good for inputting
GPIOI0. To use as the CFDEN# pin, set bits [1:0] of the
GPIOI pin function register to “Function 1 other than
GPIO.”
x GPIOI0 I/O pin (Pin function right after reset)
x SDMGPO: General-purpose output for SD card
(Function 2 of other than GPIO)
This pin has the following functions:
x CFDDIR: Data bus directional instruction output for
CF
When CF data is read, this pin becomes Low. Also, this
pin, when reset, becomes good for inputting GPIOI1. To
use as the CFDDIR pin, set bits [3:2] of the GPIOI pin
function register to “Function 1 other than GPIO.”
x GPIOI1 I/O (Pin function right after reset)
USB Device internal operation setting pin
USB Device D- I/O
USB Device D+ I/O
USB Device VBUS input
Analog signal input
This pin has the following functions:
x GPIOA0 I/O (Pin function right after reset)
x TXD1: UART1 transmit data output (Function 1 of
other than GPIO)
This pin has the following functions:
x GPIOA1 I/O (Pin function right after reset)
x RXD1: UART1 receive data input (Function 1 of other
than GPIO)
This pin has the following functions:
x GPIOA2 I/O (Pin function right after reset)
x RTS1: UART1 request to send output (Function 1 of
other than GPIO)
