F81867 Datasheet, PDF (207/315 Pages) Feature Integration Technology Inc. – 6 UARTs μSuper IO With 128 Bytes FIFO and Power Saving Functions

F81867
IRQ_MODE1 and IRQ_MODE0 will select the UART5 interrupt mode if IRQ
sharing is enabled.
00 : Sharing IRQ active low Level mode.
3
IRQ_MODE1
R/W LRESET# 0 ^{01 : Sharing IRQ active high edge mode.}
10 : Sharing IRQ active high Level mode.
11 : Reserved.
This bit is effective at IRQ is sharing with the other device (IRQ_SHARE, bit 1).

7.20 μC Side Registers
The μC side registers are basically accessed by μC with the MOVX instruction. Every device (peripheral) has its
own base address. The address mapping is list as following table.
