TMS320C6455的看门狗如何使用

Other Parts Discussed in Thread: TMS320C6455
在使用TMS320C6455的看门狗的时候,当看门狗定时器溢出时应当如何使DSP复位?
一般的器件,当看门狗定时器溢出时,系统可以自动复位,因为在芯片内部,看门狗定时器溢出的信号可用作芯片的复位信号,但是我查询了6455的数据手册关于看门狗的部分,没有找到关于看门狗定时器溢出时DSP自动复位的描述,只有以下这段描述:

    spru968.pdf  page28.

4.1 Timer Output Signal and Timer Interrupt Signal in Watchdog Mode

When the periodic service sequence is not met, the timer counter increments
until it matches the period and times out. During a time out, a pulse will be
asserted on the timer output pin, and an internal maskable interrupt (TINTLO)
will be triggered. The timer output pin can be externally connected to the NMI
(non-maskable interrupt) pin of the device. Note that the timer pulse width
must be configured to generate an active low pulse long enough for the CPU
to recognize it as a NMI pulse. The pulse width is configured using the PWID
bits of the timer control register (TCR).

似乎是说要将timer output pin连接到NMI pin才能实现看门狗复位的功能,而我设计的PCB如今没有将这两个管脚相连,是不是就没有办法使用看门狗了?器件内部没有相应的连接机制吗?
TMS320C6455的这个设计,是不是有点不同寻常呢?
