Figure 16-6. TIM Counter Modulo Registers (TMODH and TMODL)
The read/write TIM modulo registers (TMODH and TMODL) contain the
modulo value for the TIM counter. When the TIM counter reaches the
modulo value, the overflow flag (TOF) becomes set, and the TIM counter
resumes counting from $0000 at the next timer clock. Writing to the high
byte (TMODH) inhibits the TOF bit and overflow interrupts until the low
byte (TMODL) is written. Reset sets the TIM counter modulo registers.
Reset the TIM counter before writing to the TIM counter modulo registers.
