The V
Bit 4 of the configuration register ($001F) is a reserved bit on the
MC68HC08JT8. The bit will always read as zero.
On the MC68HC908JB8, bit 4 of the configuration register is the low-
voltage inhibit disable bit, LVID.
The two registers at $FE08 and $FE09 are reserved locations on the
MC68HC08JT8.
On the MC68HC908JB8, these two locations are the FLASH control
register and the FLASH block protect register respectively.
