11.2.32 Configuration Register 28 (CR28)
When the device is in Extended Function mode and EFIR is 28, the CR28 register can be accessed
through EFDR. Default = 43H if CR6 bit 2 = 1; default = 00H if CR16 bit 2 = 0. The bit definitions are
as follows:
URAIQS3-URAIQS0 (Bit 7-bit 4): Allocate interrupt resource for UART A.
URBIQS3-URBIQS0 (Bit 3-bit 0): Allocate interrupt resource for UART B.
11.2.33 Configuration Register 29 (CR29)
When the device is in Extended Function mode and EFIR is 29, the CR29 register can be accessed
through EFDR. Default = 62H if CR6 bit 2 = 1; default = 00H if CR16 bit 2 = 0. The bit definitions are
as follows:
FDCIQS3-FDCIQS0 (Bit 7-bit 4): Allocate interrupt resource for FDC.
IQNIQS3-IQNIQS0 (Bit 3-bit 0): Allocate interrupt resource for IRQIN.
11.2.34
When the device is in Extended Function mode and EFIR is 2AH, the CR2A register can be accessed
through EFDR. This register default value is 00
