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 $0FFF(HD404874, HD404864)), ($0000 to $1FFF (HD404888, HD404898,
HD404878, HD404868, HCD404878)), ($0000 to $2FFF (HD4048812, HD4048912)), ($0000 to $3FFF
(HD404889, HD404899, HCD404889, HCD404899, HD4074899, HD4074889, HD4074869))
