22.10.3 TIM Counter Modulo Registers
MC68HC908GR8 — Rev 4.0
MOTOROLA
NOTE:
Address: T1MODH, $0023 and T2MODH, $002E
Address: T1MODL, $0024 and T2MODL, $002F
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.
