0x200002 FlashCtlCnt_M
0x200003 FlashCtlCnt_L
Address Register Name
This register is enabled when the FlashChipErs bit, FlashSctErs bit or FlashWrEnb bit of the FlashCtl Register
is set alone. It is disabled when two or more bits are set.
When setting them in the unit of byte, conform to the order of FlashCtlCnt_H (higher order byte), FlashCtlCnt_M,
and FlashCtlCnt_L (lower order byte). On completion of writing to the lower order byte, setting of this register
is enabled.
Pulse width (Default value)
FlashChipErs: 40ns x 0x3FFFFF = 167.8ms
FlashSctErs:
FlashWrEnb: 40ns x 0x000190 = 16.0 s
40ns x 0x0FFFFF = 41.9ms
