Set the IFSR20 bit in the IFSR2A register to "1" after reset and set the PACR2 to PACR0 bits in the PACR
register to "011
Set the IFSR20bit in the IFSR2A register to "1" after reset and set the PACR2 to PACR0 bits in the PACR
register to "010
Immediate values should be set in the registers containing write-only bits. When establishing a new value
by modifying a previous value, write the previous value into RAM as well as the register. Change the
contents of the RAM and then transfer the new value to the register.
When setting flash memory (128K+4K) version and Mask ROM version, follow the procedure below to set
the LPCC0 and LPCC1 registers after reset.
