TIMB Counter
Modulo Registers
19-timb
MOTOROLA
NOTE:
The read/write TIMB modulo registers contain the modulo value for the
TIMB counter. When the TIMB counter reaches the modulo value, the
overflow flag (TOF) becomes set, and the TIMB 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 TIMB counter modulo registers.
Reset the TIMB counter before writing to the TIMB counter modulo
registers.
