Definable area: 00h ≤ n ≤ 01h
Function: Set input or output for general-purpose I/O ports.
Port input / output is set by value of 'a'. Bit assignment is as follows:
Caution: I/O port is intended for simple peripheral switches and for controlling lights, etc,
and should not be used for applications where high reliability is required.
Definable area: 00h ≤ n ≤ 01h
Function: Output data to general-purpose I/O port.
Output data is set by value of 'a'. Bit assignment is as follows:
Definable area: 00h ≤ n ≤ 01h
Function:
The following data is transmitted from the RS-232 interface:
Response time varies depending on the state of the receive buffer.
