This output is the Column Address Strobe signal for the
DRAM banks (2 and 3). It represents a secondary function
for I/O port PIO2[1].
This output is the Write Enable High signal for the DRAM
banks (2 and 3). It represents a secondary function for I/O
port PIO2[3].
This output is the Write Enable Low signal for the DRAM
banks (2 and 3). It represents a secondary function for I/O
port PIO2[0].
This input pin controls insertion of wait cycles. It represents
a secondary function for I/O port PIO2[7].
This input is a bus request signal from an external device. It
represents a secondary function for I/O port PIO7[6].
This output is an acknowledgment signal to a bus request
signal from an external device. It represents a secondary
function for I/O port PIO7[7].
This input is an external fast interrupt request (FIQ). When
accepted, the request is processed as an FIQ exception.
These inputs are external interrupt requests. They represent
secondary functions for I/O port PIO3[7:0].
These pins function as capture trigger input pins for Flexible
Timer (FTM) channels 5 - 0 in capture (CAP) mode. They
represent secondary functions for I/O port PIO4[5:0].
These pins function as output pins for Flexible Timer(FTM)
channels 5 - 0 in compare out (CMO) or pulse width
modulation (PWM) mode. They represent secondary
functions for I/O port PIO4[5:0].
These pins function as Flexible Timer (FTM) channel 1 and
0 clock input pins. They represent secondary functions for
I/O port PIO4[7:6].
This output is the transmit data for the Asynchronous Serial
Interface (ASI). It represents a secondary function for I/O
port PIO5[7].
This input is the receive data for the Asynchronous Serial
Interface (ASI). It represents a secondary function for I/O
port PIO5[6].
This output is the transmit data for the Clock Synchronous
Interface 0(CSI0). It represents a secondary function for I/O
port PIO5[2].
This input is the receive data for the Clock Synchronous
Interface 0 (CSI0). It represents a secondary function for I/O
port PIO5[1].
