2:0
Selection of the 32-bit Counter Modulo to generate RTTINC2 Flag
0 The RTTINC2 flag never rises
1 The RTTINC2 flag is set when CRTV modulo 64 equals 0
2 The RTTINC2 flag is set when CRTV modulo 128 equals 0
3 The RTTINC2 flag is set when CRTV modulo 256 equals 0
4 The RTTINC2 flag is set when CRTV modulo 512 equals 0
5 The RTTINC2 flag is set when CRTV modulo 1024 equals 0. Example: If RTPRES=32 then RTTINC2 flag rises once per second if the slow clock is 32.768 kHz.
6 The RTTINC2 flag is set when CRTV modulo 2048 equals 0
7 The RTTINC2 flag is set when CRTV modulo 4096 equals 0
