Mode 0 configures Timer 0 as an 13-bit Timer which is set up as an 8-bit Timer (TH0
register) with a modulo 32 prescaler implemented with the lower five bits of TL0 register
(see Figure 35). The upper three bits of TL0 register are indeterminate and should be
ignored. Prescaler overflow increments TH0 register.
Mode 1 configures Timer 0 as a 16-bit Timer with TH0 and TL0 registers connected in
cascade (see Figure 36). The selected input increments TL0 register.
