performance monitoring. The overflow of each counter is reflected by an
Overflow Indication Bit, and can trigger an interrupt if the corresponding
Overflow Interrupt Enable Bit is set. This is shown in Table 24.

Several internal counters are used to count different events for
The internal counters can be updated in two ways:
• Auto-Update: Content in the internal counters is transfered to indi-
rect registers every one second automatically if the AUTOUPD bit
is ‘1’;

ADDR[3:0] bits. The LINKSEL[2:0] bits select the link and the ADDR[3:0]
bits select the specific PMON indirect register. Data read from the indi-
rect register is held in the DAT[7:0] bits.
• Manual-Update: Content in the internal counters is transfered to
All the internal counters will be resetted after the update and will start
The indirect registers are addressed by the LINKSEL[2:0] and
indirect registers when there is a transition from ‘0’ to ‘1’ on the
UPDAT bit, no matter whether the AUTOUPD bit is ‘1’ or ‘0’.
