CHAPTER 11 16-BIT RELOAD TIMER
MB90560 series
11.3 16-Bit Reload Timer Pins
This section describes the pins of the 16-bit reload timer and provides a pin block
diagram.

16-bit reload timer pins
The pins of the 16-bit reload timer are shared with the general-purpose ports. Table 11.3-1 lists
the functions of the pins, I/O format, and settings required to use the 16-bit reload timer.
