The instruction that sets bit PCON.1 to HIGH, is the last
one executed before entering the Power-down mode. In
Power-down mode the oscillator of the P8xC592 is
stopped. If the CAN-controller is in use, it is recommended
to set it into Sleep mode before entering Power-down
mode. However, setting PCON.1 to HIGH also sets the
Sleep bit (CAN-controller Command Register bit 4) to
HIGH.
The P8xC592 leaves Power-down mode either by a
hardware reset or by a CAN Wake-Up interrupt
(due to activity on the CAN-bus),
if the SIO1 (CAN) interrupt source is enabled
(contents of register IEN0 = 1X1XXXXXB).

A hardware reset affects the whole P8xC592, but leaves
the contents of the on-chip RAM unchanged
(CAN-controller-and CPU's SFRs are reset, see
Section 13.5.2, Chapter 17 and Table 40). A CAN
Wake-Up interrupt during Power-down mode causes a
reset output pulse with a width of 6144 machine cycles
(4.6 ms with f
the CAN-controller of the P8xC592 is reset (i.e. the
contents of all CAN-controller registers are preserved).
A capacitance connected to the RST pin can be used to
lengthen the internally generated reset pulse. If the pulse
exceeds 8192 machine cycles, the CAN-controller part is
reset too.
