W83L951DG/W83L951FG
- 40 -
Bit0: Serial IRQ 0 Generate Start Bit
W83L951DG/FG hardware checks this bit in every starting of Serial IRQ procedure. If this bit is high,
W83L951DG/FG will generate Serial IRQ corresponding to OBF0 SIRQ Number @SIRQ. This bit
clears as low automatically after W83L951DG/FG receives request and enters Serial IRQ procedure.
This bit is set as high in writing this bit and data is written to Data Bus Buffer 0 Register.
This bit is to provide the method to generate Serial IRQ that is needless through writing to Data Bus
Buffer 0 Register.
6.2.1.6
Serial IRQ 0 Number (SIRQ0) (Default Value: 0000_0000)
Bit7~4: Serial IRQ 01 Number
If transmission is proceeding, IRQ number will be changed in next transmission. Set as 0000, SIRQ01
is disabled.
Bit3~0: Serial IRQ 00 Number
If transmission is proceeding, IRQ number will be changed in next transmission. Set as 0000, SIRQ00
is disabled.
6.2.1.7
Serial IRQ 1 Number (SIRQ1) (Default Value: 0000_0000)
Bit7~4: Serial IRQ 11 Number
If transmission is proceeding, IRQ number will be changed in next transmission. Set as 0000, SIRQ11
is disabled.
Bit3~0: Serial IRQ 10 Number
If transmission is proceeding, IRQ number will be changed in next transmission. Set as 0000, SIRQ10
is disabled.
6.2.1.8
Keyboard Control Register (KBCCON)(Default Value: 0000_0001)
Bit7~5: Serial IRQ Hold Counter for Serial IRQ Generate Function
000: Generate 1 cycle of Serial IRQ.
001: Generate 2 cycles of Serial IRQ.
010: Generate 3 cycles of Serial IRQ.
