NOTES:
1.
PORT90 interrupt function is controlled by IOCF Bit 3. It is a falling edge or rising edge trigger
(controlled by CONT register Bit7).
2. PORT9 (1~3) interrupt functions are controlled by IOCF Bits 4, 5, 6). They are falling edge triggers.
7.4 Application notes
1
Call-table instruction:
Because the call-table instruction can only change the Program Counter's bit7 ~ bit0 at each time,
only 256 addresses can be searched once.
But each program page contains 1024 addresses, if call each 256 addresses as a zone, Then each
page constitutes by four zones.
When a table overlaps two zones, a bug would occur during address searching.
So the member of program must examine the .LST file at any time, the .LST file will jot down the
information that Assembler generated, for example source code, the coding of instruction ,
instruction address, error message etc.

The system frequency must adds a latency time ( 14.33 MHz about 250 ms
450 ms.). After RA register was setting, it will offer the stable system frequency for the operation
Operation requirement for the CPU
17.91 MHz about
