Registers - Toshiba TX49 TMPR4937 Manual

14.4 Registers

The base address for the ACLC registers is described in section 4.2. Only word (32-bit) accesses are
allowed. These registers return to their initial values when the module gets reset by power-on or
configuration-register operation. The 'Disable AC-link' operation initializes the ACREGACC, ACGPIDAT,
ACGPODAT, and ACSLTEN registers while keeping the other registers.
Do not access any location which is not mentioned in this section.
All the register bits marked as 'Reserved' are reserved. The value of the reserved bit when read is
undefined. When any register is written, write to the reserved bit(s) the same value as the previous value
read.
