TIM Counter
Modulo Registers

NOTE:
Address: $004D
Address: $004E:$004F
Address: $004E:$004F
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 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.
