This bit enables or disables the tri-state outputs of UART A in power-down mode.
0
The output pins of UART A will not be tri-stated when UART A is in power-down
mode.
1
The output pins of UART A will be tri-stated when UART A is in power-down mode.
URBTRI (Bit 0):
This bit enables or disables the tri-state outputs of UART B in power-down mode.
0
The output pins of UART B will not be tri-stated when UART B is in power-down
mode.
1
The output pins of UART B will be tri-stated when UART B is in power-down mode.
8.2.6 Configuration Register 5 (CR5), default = 00H
When the device is in Extended Function mode and EFIR is 05H, the CR5 register can be accessed
through EFDR. The bit definitions are as follows:
7 6 5 4 3 2 1 0
ECPFTHR0
ECPFTHR1
ECPFTHR2
ECPFTHR3

Bit 7-4: Reserved
ECPFTHR3-0 (bit 3-0): These four bits define the FIFO threshold for the ECP mode parallel port. The
default value is 0000 after power-up.
8.2.7 Configuration Register 6 (CR6), default = 00H
When the device is in Extended Function mode and EFIR is 06H, the CR6 register can be accessed
through EFDR. The bit definitions are as follows:
