Viewing the I/O Memory
As well as a CPU and ROM/RAM, a microcomputer also contains on-chip peripheral modules. The exact
number and type of peripheral modules differ between devices but the typical modules are a DMA controller,
serial communications interface, A/D converter, integrated timer unit, bus state controller, and watchdog timer.
Registers that are mapped to the microcomputer’s address space controls the on-chip peripheral modules.
The [Memory] window enables you to look at data in continuous memory addresses as byte, word, longword,
single-precision floating-point, double-precision floating-point, or ASCII values. However, registers of different
sizes are allocated to non-continuous memory addresses in the I/O memory. To handle this memory, the HEW
has the [IO] window to facilitate checking and setting up of these kinds of registers.
