The bits 0 ~ 4 in PAGE register are used for page selection. Once the page mode being defined
(referring to the below section of “Option Control Function”), the working page is selected by the bits 0
~ 4 in the PAGE register. Hence, the user can execute "LD PAGE, value" instruction to change the
working page of the voice entry group. Not all of the bits 0 ~ 4 of PAGE register are used in different
page mode. They are listed as below table:

EN0 or EN1 is an 8-bit register that stores the rising/falling edge enable or disable status information
for all trigger pins, which determines whether each trigger pin is retriggerable, non-retriggerable,
overwrite, or non-overwrite. The 8-bit structure of this register and the rising or falling edge of the
triggers corresponding to each bit are shown above. “X” indicates a “don’t care” bit.
The TG1, 2, 5, 6 represents triggers 1, 2, 5 and 6 respectively; the “R” represents the rising edge; and
“F” represents the falling edge. When any one of the eight bits is set to “1”, the rising or falling edge of
the corresponding trigger pin can be enabled, interrupting the current state.
