UCD9224 PMBus Config Script Example

Hi,

I have a question while reading Configuration Programming of UCD Devices document I came across the following on pg 57 9.8.1 UCD9224 PMBus Config Script Example

Comment,"Write GPIO_SEQ_CONFIG [MFR 35] Input Pins: | Output Pins: Pin 26 PGOOD ActiveHigh ActivelyDrivenOutput POWER_GOOD | Turn On Dep: | Stay On Dep: | Stay On Shutdown Modes: Rail #1: Soft Off, Rail #2: Soft Off | Fault Slaves: " BlockWrite,0x7E,0xF3,0x1E000000000000000020000000000000000000C60000000000000000000000  

In the above BlockWrite example I see '20' in middle of string. Is it referring to Output E Dependency Configuration? and also, referring to pg of  UCD92xx Digital PWM System Controller PMBus Command Reference, for GPIO_SEQ_CONFIG in transaction type it says R/W Block 29 bytes but I see here 30 bytes. 

It is difficult to fathom 'C6' after middle of the BlockWrite string and also, to understand how it configures what the comment says.

Thanks,
