This read-only register is included so host development systems can identify the HCS08 derivative and
revision number. This allows the development software to recognize where specific memory blocks,
registers, and control bits are located in a target MCU.

COP Watchdog Clock Select — This write-once bit selects the clock source of the COP watchdog.
0 Internal 1 kHz LPO clock is source to COP.
1 Bus clock is source to COP.
COP Window — This write-once bit selects the COP operation mode. When set, the 0x55-0xAA write sequence
to the SRS register must occur in the last 25% of the selected period. Any write to the SRS register during the
first 75% of the selected period will reset the MCU.
0 Normal COP operation.
1 Window COP operation.
SPI1 Ports Input Filter Enable
0 Disable input filter on SPI1 port pins to allow for higher maximum SPI baud rate.
1 Enable input filter on SPI1 port pins to eliminate noise and restrict maximum SPI baud rate.
SPI2 Ports Input Filter Enable
0 Disable input filter on SPI2 port pins to allow for higher maximum SPI baud rate.
1 Enable input filter on SPI2 port pins to eliminate noise and restrict maximum SPI baud rate.
Analog Comparator to Input Capture Enable— This bit connects the output of ACMP to TPM input channel 0.
0 ACMP output not connected to TPM input channel 0.
1 ACMP output connected to TPM input channel 0.
