Section 22 AND/NAND Flash Memory Controller (FLCTL)
22.3.10 Ready Busy Timeout Counter (FLBSYCNT)
FLBSYCNT is a 32-bit read-only register.
The status of flash memory obtained by the status read is stored in the bits STAT[7:0].
The timeout time set in the bits RBTMOUT[19:0] in FLBSYTMR is copied to the bits
RBTIMCNT[19:0] and counting down is started when the FRB pin is placed in a busy state. When
values in the RBTIMCNT[19:0] become 0, 1 is set to the BTOERB bit in FLINTDMACR, thus
notifying that a timeout error has occurred. In this case, an FLSTE interrupt request can be issued
if an interrupt is enabled by the RBERINTE bit in FLINTDMACR.

Description
Indicate the flash memory status obtained by the
status read.
Reserved
These bits are always read as 0.
Ready Busy Timeout Counter
When the FRB pin is placed in a busy state, the
values of the bits RBTMOUT[19:0] in FLBSYTMR
are copied to these bits. These bits are counted
down while the FRB pin is busy. A timeout error
occurs when these bits are decremented to 0.
