default: 3
description: |
Chip select setup time, in serial clock cycles. See the TCSS field in
registers FLASHA1CR0 through FLASHB2CR0. The default corresponds to the
reset value of the register field.
cs-hold-time:
type: int
default: 3

Data valid time, in nanoseconds. See the registers DLLACR through
DLLBCR.
column-space:
type: int
default: 0
description: |
Column address bit width. Set to zero if the flash does not support
column address. See the CAS field in registers FLASHA1CR0 through
FLASHB2CR0. The default corresponds to the reset value of the register
field.
