DESCRIPTION

O Monitor output for the emulation system. Is active (LOW) whenever a reset is

applied to the microcontroller. (a reset can be forced by RESETIN, watchdog or

wake-up from DC/DC converter in off mode). A reset to the microcontroller

initializes all SFRs and port pins; it has no impact on the blocks operating from

VBAT.

I/O Port 3: P3.2 and P3.3 are configured as push-pull output only (option 3R; see

Section 6.6). Using the software input commands or the secondary port

function is possible by driving the port 3 output lines accordingly:

P3.2 secondary function: INT0 (external interrupt 0)

P3.3 secondary function: INT1 (external interrupt 1)
