B44 C954_IRQ

I

Advantech default function is used
as external 16C954 solution IC IRQ.
The pin directly connects to PXA255
GPIO32 (A16 pin). If user doesn’t
design 16C950 on CSB to expand
COM function, user could use this
pin as GPIO.

No pulling

A44 PXA_GP81

IO

GPIO pin. The pin directly connects
to PXA255 GPIO81 (F16 pin). This
GPIO pin is available for user to use.

No pulling

B45 PXA_GP82

IO

GPIO pin. The pin directly connects
to PXA255 GPIO82 (E16 pin). This
GPIO pin is available for user to use.

No pulling

A45 PXA_GP83

IO

GPIO pin. The pin directly connects
to PXA255 GPIO83 (E15 pin). This
GPIO pin is available for user to use.

No pulling

B46 PXA_GP84

IO

GPIO pin. The pin directly connects
to PXA255 GPIO84 (D16 pin). This
GPIO pin is available for user to use.

No pulling

A46 nBUF_CS1

O

Static chip selects. Chip selects to
static memory devices such as ROM
and Flash. Individually
programmable in the memory
configuration registers. nBUF_CS1
can be used with variable latency I/O
devices. Advantech default uses this
pin as storage flash chip select pin. If
no special application, Advantech
strongly suggest user to open this
pin in CSB.

B47 nBUF_CS4

O

Static chip selects. Chip selects to
static memory devices such as ROM
and Flash. Individually. nBUF_CS4
can be used with variable latency I/O
devices.
Advantech default use this pin as
companion chip chip select pin.
nBUF_CS4 pin is used for
EVA-C210 on SOM-A255F &
SOM-A2552 series. If no special
application, Advantech strongly
suggest user to open this pin in CSB.
