JTAG1_TMS

GPIO107(1)

S_GPIO2

T11

VDD_IO

JTAG1. Test Mode Select.



This is an optional JTAG interface, not enabled

by default. If enabled, it connects to Cortex-R4

only and allows the parallel debugging of the

Cortex-R4 and Cortex-M3 processors without

chaining them but using two separate JTAG

interfaces. If JTAG1 is not enabled, the debug

interface is controlled through the JTAG

dedicated interface only.

JTAG1_TRSTn

GPIO108(1)

S_GPIO3
