Timer Y is an 8-bit timer with an 8-bit prescaler and has two reload registers-Timer Y Primary and Timer
Y Secondary. Figure 12.11 shows a block diagram of Timer Y. Figures 12.12 to 12.14 show the TYZMR,
PREY, TYSC, TYPR, TYZOC, PUM, and YCSS registers.
The Timer Y has two operation modes as follows:
