(2) Entering flash E/W enable mode
The microcomputer can enter flash E/W enable mode only when it is operating in single-chip or
external extended mode. The microcomputer enters flash E/W enable mode only when the FP
pin is at the high level and the Flash Control Register 1 (FCNT1) FENTRY bit = 1, and cannot
enter flash E/W enable mode when operating in processor mode or the FP pin is low.
(3) Detecting the MOD0 and MOD1 pin levels
Whether the MOD0 and MOD1 pin levels (high or low) can be detected by inspecting the P8 Port
Data Register (H'0080 0708) MOD0DT and MOD1DT bits.
