Description

Output to I/O port. Words (16 bits) in memory can be output to one of 16 port

addresses. Words (16 bits) in the accumulators can be output to these same

16 port addresses or to an additional 48 port addresses. Note that, port4

address is multipled by 4 to get the actual port address.

OUTS, IN, INS

Example 4.14.55.1 OUT 3, * 0x0200 * 2

Outputs the content of word memory location value stored in 0x0200 to I/O port at location 0x0C (PBDIR port). Note that, address 3 converts to 3 * 4 = 0xc.
