NORMAL MODE REGISTER DESCRIPTION

Normal mode registers are used to configure and monitor the operation of the

S/UNI-MPH. Normal mode registers (as opposed to test mode registers) are

selected when A[10] is low.

Notes on Normal Mode Register Bits:

1. Writing values into unused register bits has no effect. Reading back unused

bits can produce either a logic 1 or a logic 0; hence, unused register bits

should be masked off by software when read.

2. All configuration bits that can be written into can also be read back. This

allows the processor controlling the S/UNI-MPH to determine the

programming state of the chip.

3. Writeable normal mode register bits are cleared to zero upon reset unless

otherwise noted.

Writing into read-only normal mode register bit locations does not affect

S/UNI-MPH operation unless otherwise noted.
