OR0 has this value set during reset (GPCM is the default control machine for all banks coming out of reset). All other option

GPCM address mask. Masks corresponding BR n bits. Masking address bits independently allows external
devices of different size address ranges to be used. Address mask bits can be set or cleared in any order in
the field, allowing a resource to reside in more than one area of the address map.
0 Corresponding address bits are masked.
1 Corresponding address bits are used in the comparison between base and transaction addresses.
Extended address mask. Masks the corresponding XBA bits in the BR n register, effectively extending the
address mask (AM) by 2 bits.
0 LBCTL is asserted upon access to the current memory bank.
1 LBCTL is not asserted upon access to the current memory bank.
access handled by the GPCM, provided that ACS ≠ 00 (when ACS = 00, only LWE is affected by the setting
of CSNT). This helps meet address/data hold times for slow memories and peripherals.
0 LCS n and LWE are negated normally.
1 LCS n and LWE are negated one quarter of a bus clock cycle earlier.
Address to chip-select setup. Determines the delay of the LCS n assertion relative to the address change
when the external memory access is handled by the GPCM. At system reset, OR0[ACS] = 11.

LCS n is output at the same time as the address lines. Note that this overrides the
value of CSNT such that CSNT=0.
Reserved.
LCS n is output a quarter bus clock cycle after the address lines.
LCS n is output a half bus clock cycle after the address lines.
