GPODAT
Bit
Description
GPO[15:0]
[15:0]
When the port is configured as input port, the corresponding bit is the pin state.
When the port is configured as output port, the pin state is the same as the
corresponding bit. When the port is configured as functional pin, the undefined
value will be read.
GPOPUD
Bit
Description
GPO[n] [2n+1:2n]
n = 0~15
00 = pull-up/down disabled
01 = pull-down enabled
10 = pull-up enabled
11 = Reserved.
GPOCONSLP
Bit
Description
Initial State
GPO[n] [2n+1:2n]
n = 0~15
00 = output 0
01 = output 1
10 = input
11 = Previuos state
00
GPOPUDSLP
Bit
Description
GPO[n] [2n+1:2n]
n = 0~15
00 = pull-up/down disabled
01 = pull-down enabled
10 = pull-up enabled
11 = Reserved.
Note
1. When the ports are set to memory interface signals, the pull-up/down are disabled
2. When the ports are set to memory interface signals, their states are controlled by MEM0CONSTOP in
stop mode and MEM0CONSLP0 in sleep mode
