R/W
Bit Bit Name Initial Value Slave Host Description
1 HBTWIE 0
R/W  BTDTR Host Write Start Interrupt Enable
Enables or disables the HBTWI interrupt which is an
IBFI3 interrupt source to the slave.
0: BTDTR host write start interrupt is disabled.
1: BTDTR host write start interrupt is enabled.
0 HBTRIE 0
R/W  BTDTR Host Read End Interrupt Enable
Enables or disables the HBTRI interrupt which is an
IBFI3 interrupt source to the slave.
0: BTDTR host read end interrupt is disabled.
1: BTDTR host read end interrupt is enabled.
Note: * Don't care.
16.3.22 BT Control Status Register 1 (BTCSR1)
BTCSR1 is one of the registers used to implement the BT mode. The BTCSR1 register contains
the bits used to enable or disable interrupts to the slave (this LSI). The IBFI3 interrupt is enabled
by setting the IBFIE3 bit in HICR2 to 1.
R/W
Bit Bit Name Initial Value Slave Host Description
7 RSTRENBL 0
R/W  Slave Reset Read Enable
The host reads 0 from the BMC_HWRST bit in
BTIMSR. When this bit is set to 1, the host can read
1 from the BMC_HWRST bit.
0: Host always reads 0 from BMC_HWRST
1: Host can reads 0 from BMC_HWRST
6 HRSTIE 0
R/W  BT Reset Interrupt Enable
Enables or disables the HRSTI interrupt which is an
IBFI3 interrupt source to the slave.
0: BT reset interrupt is disabled.
1: BT reset interrupt is enabled.
5 IRQCRIE 0
R/W  B2H_IRQ Clear Interrupt Enable
Enables or disables the IRQCRI interrupt which is
an IBFI3 interrupt source to the slave.
0: B2H_IRQ clear interrupt is disabled.
1: B2H_IRQ clear interrupt is enabled.
