Description
Initial State
P6.0
[1:0]
00 = Schmitt input or serial data input(SIORXD0) mode for SIO.
For the case of SIORXD0, the SIO 0 should be enabled.
Otherwise, this bit will be input port.
01 = C-MOS push-pull output mode
10 = N-ch open-drain output mode
00
P6.1
[4:2]
000 = Schmitt input or serial clock input(SIOCLK0) mode for SIO
For the case of SIOCLK0, the SIO 0 should be enabled.
Otherwise, this bit will be input port.
001 = C-MOS push-pull output mode
010 = N-ch open-drain output mode
101 = C-MOS push-pull serial clock output (SIOCLK0) for SIO 0
110 = N-ch open-drain serial clock output (SIOCLK0) for SIO 0
000
P6.2
[7:5]
000 = Schmitt input mode
001 = C-MOS push-pull output mode
010 = N-ch open-drain output mode
101 = C-MOS push-pull serial data output (SIOTXD0) for SIO 0
110 = N-ch open-drain serial data output (SIOTXD0) for SIO 0
000
P6.3
[9:8]
00 = Schmitt input mode
01 = C-MOS push-pull output mode
10 = Wait signal(nWAIT) input for the external interface
11 = Ready signal(nSIORDY) input or output for SIO0,1
00
P6.4
[11:10]
00 = Schmitt input or serial data input (SIORXD1) mode for SIO.
For the case of SIORXD1, the SIO 1 should be enabled.
Otherwise, this bit will be input port.
01 = C-MOS push-pull output mode
10 = N-ch open-drain output mode
00
P6.5
[14:12]
000 = Schmitt input or serial clock input (SIOCLK1) mode for
SIO For the case of SIOCLK1, the SIO 1 should be enabled.
Otherwise, this bit will be input port.
001 = C-MOS push-pull output mode
010 = N-ch open-drain output mode
101 = C-MOS push-pull serial clock output (SIOCLK1) for SIO 1
110 = N-ch open-drain serial clock output(SIOCLK1) for SIO 1
000
P6.6
[17:15]
000 = Schmitt input mode
001 = C-MOS push-pull output mode
010 = N-ch open-drain output mode
101 = C-MOS push-pull serial data output (SIOTXD1) for SIO 1
110 = N-ch open-drain serial data output (SIOTXD1) for SIO 1
000
P6.7
[18]
0 = Schmitt input mode or external interrupt (EINT3) input mode.
For the case of EINT3, the EINT3 should be enabled. Otherwise,
this bit will be input port.
