Bits 5
7 of PAGE register are reserved; bits 0
4 are used for page selection. The user must set the
page mode configuration described in the Option Control declaration. Once the page mode is
decided, the working page is selected by the bits 0
4 of PAGE register. Hence, the user can execute
"LD PAGE, value" instruction to change the working page of the interrupt vector/label. Not all of the
bits 0
4 of PAGE register are used in different page mode; they are listed below.

A "1" means "enabled", while a "0" means "disabled" for that edge of the particular TG pin. For
example, the instruction "LD EN0, 0x0F" enables all the falling edge triggers of TG1
TG4, while
disabling all the rising edge triggers of TG1
TG4. The user can modify the EN0 and EN1 registers
during operation of the W58300 to achieve various kinds of trigger functions, like retriggerable or not,
one shot or level hold play mode, etc.
That is to say, users can change the contents of EN0, EN1 register during synthesis at will to
determine which trigger pin is to be enabled or disabled for its falling/rising edge.

STA
The STOP register is used to control the status of the STPA
STPH pins. For example, STB = 1
means that pin is in high state and STB = 0 means low state.
6. R0
R7 Registers
These eight registers are general purpose registers. They can be used to hold interrupt vector/label.
R0 is a special register which can be incremented by "INC" instruction.
