5.6
A microcomputer 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.
5.6.1
To open the [IO] window, select [View -> CPU -> IO] or click the [View I/O] toolbar button (
match the on-chip peripheral modules organize the I/O register information. When the [IO] window is first
opened, only a list of module names is displayed.
5.6.2
To display the names, addresses, and values of the I/O registers, click the [+] mark at the left of the module name
or select the module name by clicking on it or using the cursor keys and press the [->] key. The module display
will expand to show the individual registers of that peripheral module and their names, addresses, and values.
Clicking the [-] mark at the left of the expanded module name or pressing the [<-] key will close the I/O register
display.
For a display in the bit level, click the [+] mark at the left of the register name or select the register name by
clicking on it or using the cursor keys and press the [->] key. The register display will expand to show the names
of register bits and values. Clicking the [-] mark at the left of the expanded register name or pressing the [<-] key
will close the register bits display.
