Description
Key Wakeup Level 1 and 0
Sets the port 6 input level. The input level of port-6
multiplexing pins is also changed by these settings.
00: Port 6 is in the standard input level
01: Port 6 is in input level 1
10: Port 6 is in input level 2
11: Port 6 is in input level 3
Port 6 Input Pull-Up MOS Extra (P6PUE)
Controls and selects the current specification for the
port 6 input pull-up MOS.
0: Standard current specification
1: Current limited specification
Reserved
Only 0 should be written to this bit.
Shutdown Enable
0: Host interface pin shutdown function disabled
1: Host interface pin shutdown function enabled
When the shutdown function is enabled, host
interface pin functions can be halted, and the pins
placed in the high-impedance state, according to the
state of the HIFSD pin.
