Slave Host Description
3 SDWNB 0 R/W ⎯ LPC Software Shutdown Bit
Controls LPC interface shutdown. For details of the LPC
shutdown function, and the scope of initialization by an
LPC reset and an LPC shutdown, see section 20.4.4, LPC
Interface Shutdown Function (LPCPD).
0: Normal state
[Clearing conditions]
• Writing 0
• LPC hardware reset or LPC software reset
• LPC hardware shutdown
(falling edge of LPCPD signal when SDWNE = 1)
• LPC hardware shutdown release
(rising edge of LPCPD signal when SDWNE = 0)
1: LPC software shutdown state
[Setting condition]
Writing 1 after reading SDWNB = 0
2 PMEB 0 R/W ⎯ PME Output Bit
Controls PME output in combination with the PMEE bit.
For details, refer to description on the PMEE bit in HICR0.
1 LSMIB 0 R/W ⎯ LSMI Output Bit
Controls LSMI output in combination with the LSMIE bit.
For details, refer to description on the LSMIE bit in HICR0.
0 LSCIB 0 R/W ⎯ LSCI output Bit
Controls LSCI output in combination with the LSCIE bit.
For details, refer to description on the LSCIE bit in HICR0.
