Figure 6.4-6 Boot From Ldrom Without Iap Support; Figure 6.4-7 Boot From Aprom Without Iap Support - Nuvoton ISD94124BYI Technical Reference Manual

This mode does not support IAP -- because it cannot access APROM, and the LDROM has only 4
KB – one page size. In this mode remapping is not supported.
6.4.4.2.4 Boot from APROM without IAP support
By writing 0b11 into CBS[1:0] bits in CONFIG0, the ISD94100 device will load the system vector
table from APROM space 0x0000_0000 - 0x0000_01FF. In this mode the MCU boots from
APROM. And the MCU can only the access APROM, and data Flash if the partition for data flash
exists, as shown in Figure 6.4-7.
