946 / 1158 page ![]() Section 21 Flash Memory (0.18- µm F-ZTAT Version) Rev.1.00 Jun. 07, 2006 Page 894 of 1102 REJ09B0294-0100 (2) Flash Pass and Fail Parameter (FPFR: General Register R0L of CPU) FPFR indicates the return values of the initialization, programming, and erasure results. The meaning of the bits in FPFR varies depending on the processing. (a) Initialization before programming/erasing FPFR indicates the return value of the initialization result. 7 6 5 4 3 0 SF 2 1 FQ Bit Bit Name Bit Bit Name Initial Value R/W Description 7 to 2 Unused These bits return 0. 1 FQ R/W Frequency Error Detect Compares the specified CPU operating frequency with the operating frequencies supported by this LSI, and returns the result. 0: Setting of operating frequency is normal 1: Setting of operating frequency is abnormal 0 SF R/W Success/Fail Returns the initialization result. 0: Initialization has ended normally (no error) 1: Initialization has ended abnormally (error occurs) (b) Programming FPFR indicates the return value of the programming result. 7 6 MD 5 EE 4 FK 3 0 SF 2 WD 1 WA Bit Bit Name Bit Bit Name Initial Value R/W Description 7 Unused Returns 0. |
