Memory Map

ROM Memory Map

The ROM memory map is shown in figure 1 and is described below.

Vector address area ($0000 to $000F): When an MCU reset or interrupt handling is performed, the

program is executed from the vector address. A JMPL instruction should be used to branch to the start

address of the reset routine or the interrupt routine.

Zero page subroutine area ($0000 to $003F):A branch can be made to a subroutine in the area $0000 to

$003F with the CAL instruction.

Pattern area ($0000 to $0FFF): ROM data in the area $0000 to $0FFF can be referenced as pattern data

with the P instruction.

Program area ($0000 to $03FF (HD404081, HD40A4081, HD40C4081)), ($0000 to $07FF (HD404372,

HD40A4372, HD40C4372, HD404382, HD40A4382, HD40C4382, HD404082, HCD404082,

HD40A4082, HD40C4082, HCD40C4082)), ($0000 to $0FFF (HD404374, HD40A4374, HD40C4374,

HD404384, HD40A4384, HD40C4384, HD407A4374, HD407C4374, HD407A4384, HD407C4384,

HD404084, HCD404084, HD40A4084, HD40C4084, HCD40C4084)), ($0000 to $1FFF (HD404388,

HD40A4388, HD40C4388)), ($0000 to $3FFF (HD404389, HD40A4389, HD40C4389, HD407A4389,

HD407C4389)).
