4.5.41 Device ID register
4.5.42 Flash configuration register
Table 50.
This device ID register is a read-only register and contains the device ID for each
LPC122x part. This register is also read by the ISP/IAP commands (see
and
Table 51.
Depending on the system clock frequency, access to the flash memory can be configured
with various access times by writing to the FLASHCFG register at address 0x5006 0028.
Remark: Settings in this register only have an effect when the FLASH_OVERRIDE bit in
the PRESET_CTRL register (see
