3.2 The Software Timing
Whenever a watchdog timer time-out occurs or when a software reset is requested by
writing to the RST_CTL.DO_SW_RST bit the PNX15xx Series system is reset. Both
are referred as software reset. As seen in the previous
hold the POR_IN_N or the RESET_IN_N signal for at least 100 s. Therefore the
software reset mechanism implements an internal counter that allows to assert the
peri_rst_n signal for 100 s. Similarly to the hardware reset the sys_rst_out_n is also
asserted until the TM3260 CPU releases it. The internal counter uses the initial 27
MHz to estimate 100 s.
