It is in the middle of the final paragraph of 9.11.1 Microcode Update, immediately preceding Table 9-7 "The total size field of the microcode update header specifies the encrypted data size plus the header size; its value must be in multiples of 1024 bytes (1 KBytes)." ~Andrew (I've lost count of how many times I've read this chapter over the course of developing this series...)
