Trying to get USART going.
I can see data in the DATA reg if I poll it and the RXCIF bit getting set in STATUS, but my ISR is not getting called.
I have set the RX int to low level and enabled low level int in PMIC.
Anything else I need to do???
USARTC0.CTRLC = USART_CHSIZE_8BIT_gc; //no partiy, 1 stop, 8 data bits
USARTC0.BAUDCTRLA = 12; //12 = 4800 with 2meg clock, clk2X set to zero and BScale set to 0
USARTC0.BAUDCTRLB = 0;
USARTC0.CTRLA = USART_RXCINTLVL_LO_gc; //rx ints only
USARTC0.CTRLB = USART_RXEN_bm; // rx enable
PMIC.CTRL = PMIC_LOLVLEN_bm; //Enable low level
