The MC68HC05B4 is a device similar to the MC68HC05B6, but without EEPROM and having a
reduced ROM size of 4 kbytes. The entire MC68HC05B6 data sheet applies to the MC68HC05B4,
with the exceptions outlined in this appendix.

Section 3.5, ‘EEPROM’, therefore, does not apply to the MC68HC05B4, and the register at
address $07 only allows the user to select whether or not the ECLK should appear at PC2, using
bit 3 of $07. All other bits of this register read as ‘0’.
