0: Input (Default)
1: Output
This register is used to specify the selection of input or output of P1.0 - P1.3 pins of port P1. A
"0" selects input, while a "1" gives the output selection. Default value of IOR1 is 00h(after power
on, or reset), which indicates the selection of all inputs, to avoid possible I/O conflicts with
external circuits that may cause large current consumption.
Example :
LD IOR1, 1100b ; input pins : P1.0, P1.1
; output pins : P1.2, P1.3
Once a pin was configured as input pin and Hi impedance (by set 0 in related bit of PCR1 or
PCR2 register), this pin
must
not
leave as floating to avoid large standby current.
IOR2 ( I/O Register 2 )
3
2
P2.3
P2.2
Same as IOR1 except for the selection of port P2, rather than port P1.
Example :
LD IOR2, 1111b ; port 2 is configured as output port
