This "Reset-upon-Read" register, along with the
"PMON CP-Bit Error Count Register - MSB" (Address
= 0x58) contains a 16-bit representation of the num-
ber of "CP-bit Errors that have been detected by the
Receive DS3 Framer block (within the chip), since the
last read of these registers. This register contains the
MSB (or Upper-Byte) value of this 16 bit expression.

Each of the PMON registers are 16 bit "Reset-upon-
Read" registers. More specifically, whenever the Mi-
croprocessor intends to read a PMON register, there
are two things to bear in mind.
1. This Microprocessor is going to require two read
accesses in order read out the full 16-bit expres-
sion of these PMON registers.
2. The entire 16-bit expression (of a given PMON
register) is going to be reset, immediately after
225
