2.6.3.1
Power-On Reset (PORESET) Pin
Asserting PORESET initiates the power-on reset flow. PORESET must be asserted externally for at least 32 CLKIN cycles after
VDD and VDDIO are both at their nominal levels.
2.6.3.2
Reset Configuration
The MSC8144 has two mechanisms for writing the reset configuration:
Through the I2C port
Through external pins
Through internal hard coded
Twenty-three signals (see Section 1 for signal description details) are sampled during the power-on reset sequence to define the
Reset Word Configuration Source and operating conditions:
RCW_SRC[2–0]
RC[16–0]
The RCFG_CLKIN_RNG pin must be valid during power-on or hard reset sequence. The STOP_BS pin must be always valid
and is also sampled during power-on reset sequence for RCW loading from an I2C EEPROM.
