HC908JL8AD/D Reserved Registers The two registers at $FE08 and $FFCF are reserved locations on the MC68HC08JL8. On the MC68HC908JL8, these two locations are the FLASH control register and the FLASH block protect register respectively. Mask Option Register The mask option register at $FFD0 is read only. The value is defined by mask option (hard-wired connections) specified at the time as the ROM code submission. Freescale Semiconductor, Inc... On the MC68HC908JL8, the MOR is implemented as a FLASH, which can be programmed, erased, and read. Monitor ROM The monitor program (monitor ROM: $FE10–$FFCE) on the MC68HC08JL8 is for device testing only. $FC00–$FDFF are unused.

KEYBOARD INTERRUPT FF KBI7 KEYBOARD INTERRUPT REQUEST IMASKK MODEK KBIE7 TO PULLUP ENABLE Computer Operating Properly (COP) From: Page 254, 16.8.2 Stop Mode — Replace the two paragraphs: Stop mode turns off the ICLK input to the COP if the STOP_ICLKDIS bit is set in configuration register 2 (CONFIG2). Service the COP immediately before entering or after exiting stop mode to ensure a full COP timeout period after entering or exiting stop mode. After reset, the STOP_ICLKDIS bit is clear by default and ICLK is enabled during stop mode. To: Stop mode turns off the ICLK input to the COP and clears the COP prescaler. Service the COP immediately before entering or after exiting stop mode to ensure a full COP timeout period after entering or exiting stop mode. To prevent inadvertently turning off the COP with a STOP instruction, a configuration option is available that disables the STOP instruction. When the STOP bit in the configuration register has the STOP instruction is disabled, execution of a STOP instruction results in an illegal opcode reset.
