[29:28]
00 = Input
01 = Output
10 = MEM0_CData
11 = Ext. Interrupt Group8 [14]

GPPDAT
Bit
Description
GPP[14:0]
[14:0]
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.
GPPPUD
Bit
Description
GPP[n] [2n+1:2n]
n = 0~14
00 = pull-up/down disabled
01 = pull-down enabled
10 = pull-up enabled
11 = Reserved.

Bit
Description
Initial State
GPP[n] [2n+1:2n]
n = 0~14
00 = output 0
01 = output 1
10 = input
11 = Previuos state

GPPPUDSLP
Bit
Description
GPP[n] [2n+1:2n]
n = 0~14
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, their states are controlled by MEM0CONSTOP in stop
mode, MEM0CONSLP1 in sleep mode
