3.4.2 Short direct addressing
[Function]
The memory to be manipulated in the fixed space is directly addressed with the 8-bit data in an instruction word.
The fixed space where this addressing is applied is the 160-byte space FE80H to FF1FH (FE80H to FEFFH
(internal high-speed RAM) + FF00H to FF1FH (special function registers)) for the
μPD78F9221, or the 256-byte
space FE20H to FF1FH (FE20H to FEFFH (internal high-speed RAM) + FF00H to FF1FH (special function
registers)) for the
μPD78F9222 and 78F9224.
The SFR area where short direct addressing is applied (FF00H to FF1FH) is a part of the total SFR area. In this
area, ports which are frequently accessed in a program and a compare register of the timer counter are mapped,
and these SFRs can be manipulated with a small number of bytes and clocks.
When 8-bit immediate data is at 20H to FFH, bit 8 of an effective address is cleared to 0. When it is at 00H to
1FH, bit 8 is set to 1. See [Illustration] below.
