16.26 PSC2 Specific Register
16.26.1
4378C–AVR–09/08
PSC 2 Output Matrix – POM2
• Bit 7 – PCSTn : PSC Capture Software Trig bit
Set this bit to trigger off a capture of the PSC counter. When reading, if this bit is set it means
that the capture operation was triggered by PCSTn setting otherwise it means that the capture
operation was triggered by a PSC input.
The Input Capture is updated with the PSC counter value each time an event occurs on the
enabled PSC input pin (or optionally on the Analog Comparator output) if the capture function is
enabled (bit PCAEnx in PFRCnx register is set).
The Input Capture Register is 12-bit in size. To ensure that both the high and low bytes are read
simultaneously when the CPU accesses these registers, the access is performed using an 8-bit
temporary high byte register (TEMP). This temporary register is shared by all the other 16-bit or
12-bit registers.
