4.4. Pin Descriptions
CCU 3000, CCU 3001 Pin Descriptions.
Pin numbers refer to the 68–pin PLCC housing.
The functions of some pins are influenced by bit 4 of the
CCU control register (addr. 201H, copied from FFF9H at
reset: CCU control register bit 4 = ‘1’ switches the CCU
in Port Mode , CCU control register bit 4 = ‘0’ switches
the CCU in Bus Mode
In addition, some port bit functions may be changed be-
tween Normal Modeand Special Modeby setting the
specific bit in its port mode registers.
