System Resets
140
IMO (not to scale)
IMO (not to scale)
IMO (not to scale)
POR (IPOR followed by PPOR): Reset while POR is high (IMO off), then 511(+)
cycles (IMO on), and then the CPU reset is released. XRES is the same, with N=8.
PPOR (with no IPOR): Reset while PPOR is high and to the end of the next 32K
cycle (IMO off); 1 cycle IMO on before the CPU reset is released. Note that at the
3V level, PPOR tends to be brief because the reset clears the POR range register
(VLT_CR) back to the default 2.4V setting.
XRES: Reset while XRES is high (IMO off), then 7(+) cycles (IMO on), and then the
CPU reset is released.
