PSoC 3 Real Time Clock
The real time clock has a 1 pulse per second (1 pps) feature that wakes up the device from sleep mode.
Is it possible to change this period? Say I wanted a 1/2 second pulse? This should be theoretically doable because my understanding is that the RTC XTAL drives a 13 bit counter internally. A modification of the counter's period should allow for this (perhaps via register write?)
