STR3 Register Function Select 3
Selects the function of bits 7 to 4 in STR3 in
combination with the TWRE bit in LADR3L. See
description on STR3 in section 19.3.7, Status
Registers 1 to 3 (STR1 to STR3), for details.
0: Bits 7 to 4 in STR3 are status bits of the host
1: [When TWRE = 1]
SERIRQ Output Select
Selects the pin output status of host interrupt
requests (HIRQ11, HIRQ10, HIRQ9, HIRQ6, SMI,
HIRQ12, and HIRQ1) of the LPC.
0: [When host interrupt request is cleared]
1: [When host interrupt request is cleared]
interface.
Bits 7 to 4 in STR3 are status bits of the host
interface.
[When TWRE = 0]
Bits 7 to 4 in STR3 are user bits.
SERIRQ pin output is in the high-impedance
state.
[When host interrupt request is set]
SERIRQ pin output is 0.
SERIRQ pin output is 0.
[When host interrupt request is set]
SERIRQ pin output is in the high-impedance
state.
