ECC Position Specification 1 and 0
Specify the position (0/4th/8th byte) to place the ECC in
the control code area.
00: Places the ECC at the 0 to 7th byte of control code
01: Places the ECC at the 4th to 11th byte of control
10: Places the ECC at the 8th to 15th byte of control
11: Setting prohibited
Select Dividing Rates for Flash Clock
Flash Clock Select
QTSEL = 0, FCKSEL = 0: Divides a clock (Pφ)
provided from the CPG by two and uses it as FCLK.
QTSEL = 0, FCKSEL = 1: Uses a clock (Pφ)
provided from the CPG as FCLK.
QTSEL = 1, FCKSEL = 0: Divides a clock (Pφ)
provided from the CPG by four and uses it as FCLK.
QTSEL = 1, FCKSEL = 1: Setting prohibited
