Clock and Reset Signals
17.5.5.1 D[7:5Boot Chip-Select (CS0) Configuration
D[7:5] determine defaults for the global chip select (CS0), the only chip select valid at reset.
These signals correspond to bits in chip-select configuration register 0 (CSCR0).
17.5.5.2 D7—Auto Acknowledge Configuration (AA_CONFIG)
At reset, the enabling and disabling of auto acknowledge for boot CS0 is determined by the
logic level driven on D7 at the rising edge of RSTI. AA_CONFIG is multiplexed with D7
and sampled only at reset. The D7 logic level is reflected as the reset value of CSCR[AA].
Table 17-12 shows how the D7 logic level corresponds to the auto acknowledge timing for
CS0 at reset. Note that auto acknowledge can be disabled by driving a logic 0 on D7 at reset.
17.5.5.3 D[6:5]—Port Size Configuration (PS_CONFIG[1:0])
The default port size value of the boot CS0 is determined by the logic levels driven on
D[6:5] at the rising edge of RSTI, which are reflected as the reset value of CSCR[PS]. Table
17-13 shows how the logic levels of D[6:5] correspond to the CS0 port size at reset.
17.5.6 D4—Address Configuration (ADDR_CONFIG)
The address configuration signal (ADDR_CONFIG) programs the PAR of the parallel I/O
port to be either parallel I/O or to be the upper address bus bits along with various attribute
and control signals at reset to give the user the option to access a broader addressing range
