EJTAG_TRST_N
I
STI
EJTAG Test Reset.
EJTAG_TRST_N is an active-low signal for asynchronous reset of only the EJTAG/ICE controller.
EJTAG_TRST_N requires an external pull-up on the board. EJTAG/ICE enable is selected during reset using the boot con-
figuration and overrides the selection of the Primary and Alternate functions. This signal requires an external resistor, listed
in Table 14.
Primary: General Purpose I/O, GPIOP[31]
1st Alternate function: DMA finished output, DMAFIN.
JTAG_TRST_N
I
STI
JTAG Test Reset.
JTAG_TRST_N is an active-low signal for asynchronous reset of only the JTAG boundary scan control-
ler. JTAG_TRST_N requires an external pull-down on the board that will hold the JTAG boundary scan controller in reset
when not in use if selected. JTAG reset enable is selected during reset using the boot configuration and overrides the
selection of the Primary and Alternate functions.
Primary function: General Purpose I/O, GPIOP[2].
1st Alternate function: UART channel 0 ring indicator, U0RIN.
Debug
INSTP
O
Low Drive
Instruction or Data Indicator
. This signal is driven high during CPU instruction fetches and low during CPU data transac-
tions on the memory and peripheral bus.
CPUP
O
Low Drive
CPU or DMA Transaction Indicator
. This signal is driven high during CPU transactions and low during DMA transactions
on the memory and peripheral bus if CPU/DMA Transaction Indicator Enable is enabled. CPU/DMA Status mode enable is
selected during reset using the boot configuration and overrides the selection of the Primary and Alternate functions.
Primary function: General Purpose I/O, GPIOP[4].
1st Alternate function: UART channel 0 data terminal ready U0DTRN.
DMAP[0]
O
Low Drive
Active DMA channel code
. DMA debug enable is selected during reset using the boot configuration and overrides the
selection of the Primary and Alternate functions.
Primary function: General Purpose I/O, GPIOP[23].
1st Alternate function: TXADDR[1].
DMAP[1]
O
Low Drive
Active DMA channel code
. DMA debug enable is selected during reset using the boot configuration and overrides the
selection of the Primary and Alternate functions.
Primary function: General Purpose I/O, GPIOP[25].
1st Alternate function: RXADDR[1].
DMAP[2]
O
Low Drive
Active DMA channel code
. DMA debug enable is selected during reset using the boot configuration and overrides the
selection of the Primary and Alternate functions.
Primary function: General Purpose I/O, GPIOP[9].
1st Alternate function: U1SINP.
DMAP[3]
O
Low Drive
Active DMA channel code
. DMA debug enable is selected during reset using the boot configuration and overrides the
selection of the Primary and Alternate functions.
Primary function: General Purpose I/O, GPIOP[8].
1st Alternate function: U1SOUTP.
UART
U0SOUTP
I
STI
UART channel 0 serial transmit.
Primary function: General Purpose I/O, GPIOP[0]. At reset, this pin defaults to primary function GPIOP[0].
U0SINP
I
STI
UART channel 0 serial receive.
Primary function: General Purpose I/O, GPIOP[1]. At reset, this pin defaults to primary function GPIOP[1].
U0RIN
I
STI
UART channel 0 ring indicator.
Primary function: General Purpose I/O, GPIOP[2]. At reset, this pin defaults to primary function GPIOP[2] if JTAG reset
enable is not selected during reset using the boot configuration.
2nd Alternate function: JTAG boundary scan reset, JTAG_TRST_N.
U0DCRN
I
STI
UART channel 0 data carrier detect.
Primary function: General Purpose I/O, GPIOP[3]. At reset, this pin defaults to primary function GPIOP[3].
