Timer Interface Module (TIM)
11.8.3 TIM Counter Modulo Registers
11.8.4 TIM Channel Status and Control Registers
Data Sheet
142
NOTE:
The read/write TIM modulo registers 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.
Each of the TIM channel status and control registers (TSC0 and TSC1):
Register Name and Address: TMODH—$0023
Register Name and Address: TMODL—$0024
