1. The SCI module is not included on the MC9S08RC devices. This is a reserved location for those devices.

2. The analog comparator (ACMP) module is not included on the MC9S08RD devices. This is a reserved location for those

devices.

3. The SPI module is not included on the MC9S08RC/RD/RE devices. These are reserved locations on the 32K and 60K versions

of these devices. The address range $0040â$004F are RAM locations on the 16K and 8K devices. There are no

MC9S08RG8/16 devices.

High-page registers, shown in Table 4-2, are accessed much less often than other I/O and control registers

so they have been located outside the direct addressable memory space, starting at $1800.
