CHAPTER 16 SERIAL INTERFACE CHANNEL 0 (
µ
PD78054 Subseries)
(4) Interrupt timing specify register (SINT)
This register sets the bus release interrupt and address mask functions and displays the SCK0/P27 pin level
status.
SINT is set with a 1-bit or 8-bit memory manipulation instruction.
RESET input sets SINT to 00H.
Figure 16-6. Interrupt Timing Specify Register Format
Notes 1. Bit 6 (CLD) is a read-only bit.
2. When using wake-up function in the SBI mode, set SIC to 0.
3. When CSIE0 = 0, CLD becomes 0.
Caution Be sure to set bits 0 to 3 to 0.
Remark SVA : Slave address register
CSIIF0 : Interrupt request flag corresponding to INTCSI0
