27.5.3.2 Reset Configuration Register (RCON)
At reset, RCON determines the default operation of certain chip functions. All default functions defined
by the RCON values can only be overridden during reset configuration (see Section 27.6.1, “Reset
Configuration”) if the external RCON pin is asserted. RCON is a read-only register.

Reserved, should be cleared.
Chip select configuration. Reflects the default chip select configuration. The default function
of the chip select configuration can be overridden during reset configuration.
00 PF[7:5] = A[23:21] (This is the value used for this device.)
01 PF[7] = CS6 / PF[6:5] = A[22:21]
10 PF[7:6] = CS6, CS5 / PF[5] = A[21]
11 PF[7:5] = CS6, CS5, CS4
Reserved, should be cleared.
Pad driver load. Reflects the default pad driver strength configuration.
0 Partial drive strength
1 Full drive strength (This is the value used for this device.)
