7.1.2 Block Diagram
Figure 7-1 shows a block diagram of the refresh controller.
Refresh timer counter (RTCNT) can be used as an 8-bit up-counter
Selection of seven counter clock sources: ø/2, ø/8, ø/32, ø/128, ø/512, ø/2048, ø/4096
Interrupts can be generated by compare match between RTCNT and the refresh time constant
register (RTCOR)
ø/2, ø/8, ø/32,
ø/128, ø/512,
ø/2048, ø/4096
