(Refer to section Chapter “10. WATCHDOG TIMER.”) For access characteristics at address 6C16, also refer to Figure 14.3.2 in part 1. State immediately after reset for bit 3 at address 6F16 vary according to the microcomputer. (Refer to Figure 14.3.3 in part 2 ; This bit’s function of the 7735 Group differs from that of the 7733 Group.) This bit must be fixed to “0” in the 7735 Group. Do not write data to address 6216. sInternal RAM area (M37735MHBXXXFP: addresses 8016 to FFF16) At hardware reset (not including the case where the stop or wait mode is terminated)...Undefined. At software reset...Retains the state immediately before reset. When the stop or wait mode is terminated (when hardware reset is applied)...Retains the state immediately before the STP or WIT instruction is executed. ?
