Section 23 AND/NAND Flash Memory Controller (FLCTL)
23.3.2 Command Control Register (FLCMDCR)
FLCMDCR is a 32-bit readable/writable register that issues a command in command access mode,
specifies address issue, and specifies source or destination of data transfer. In sector access mode,
FLCMDCR specifies the number of sector transfers.

Address Issue Byte Count Specification 2
Specifies the number of bytes for the address data to
be issued in address stage. This bit is used together
with ADRCNT[1:0].
0: Issue the address of byte count, specified by
ADRCNT[1:0].
1: Issue 5-byte address. ADRCNT[1:0] should be set
to 00.

R/W Sector Transfer Count Specification [19:16]
These bits are extended bits of the sector transfer count
specification bits (SCTCNT) 15 to 0.
SCTCNT[19:16] and SCTCNT[15:0] are used together
to operate as SCTCNT[19:0], the 20-bit counter.
