11.1.2. Mode 1: 16-bit Counter
Mode 1 is the same as Mode 0, except that the Timer register uses all 16 bits. Refer to Fig 11-2. In this mode,
THx and TLx are cascaded; there is no prescaler.
Fig 11-2 Mode 1: 16-bit Counter
11.1.3. Mode 2: 8-bit Auto-reload
Mode 2 configures the Timer register as an 8-bit Counter (TLx) with automatic reload, as shown in Fig 11-3..
Overflow from TLx not only sets TFx, but also reloads TLx with the contents of THx, which is preset by firmware.
The reload leaves THx unchanged.
