16.8.2 TIM Counter Registers
The two read-only TIM counter registers contain the high and low bytes of the value in the counter.
Reading the high byte (TCNTH) latches the contents of the low byte (TCNTL) into a buffer. Subsequent
reads of TCNTH do not affect the latched TCNTL value until TCNTL is read. Reset clears the TIM counter
registers. Setting the TIM reset bit (TRST) also clears the TIM counter registers.
16.8.3 TIM Counter Modulo Registers
The read/write TIM modulo registers contain the modulo value for the counter. When the counter reaches
the modulo value, the overflow flag (TOF) becomes set, and the 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.

If you read TCNTH during a break interrupt, be sure to unlatch TCNTL by
reading TCNTL before exiting the break interrupt. Otherwise, TCNTL
retains the value latched during the break.
Reset the counter before writing to the TIM counter modulo registers.
