TYPESEL (Transaction Type Select). Selects the transaction type decoded for memory addresses. For
address decoding of the Memory Base address, bit 31 value is 1 regardless of TYPESEL value, thus limiting
the Memory Base Address to high 2G memory space.
0: Transactions type is LPC Memory Read/Write (default)
1: Transactions type is LPC FWH Memory Read/Write
6-3
MEMFWHID (Memory FWH ID).
• When TYPESEL is 0: Indicates selected Memory Base address bits 30-27.
• When TYPESEL is 1: indicates the IDSEL of the Firmware Memory transactions to which the PC8374L re-
sponds. The least significant bit of this field is also used as Memory Base address bit 27.
2-0
Memory Base Address 2. Indicates selected Memory Base address bits 26-24.
