W742E/C813
- 28 -
HCF.0 = 1 Hold mode was released by overflow from the divider 0.
HCF.1 = 1 Hold mode was released by underflow from the timer 0.
HCF.2 = 1 Hold mode was released by a signal change at port RC.
HCF.3 = 1 Hold mode was released by a signal change at port P1.2 (INT0 ).
HCF.4 = 1 Hold mode was released by overflow from the divider 1.
HCF.5 = 1 Hold mode was released by Serial I/O signal.
HCF.6 = 1 Hold mode was released by a signal change at port P1.3 (INT1).
HCF.7 = 1 Hold mode was released by underflow from the timer 1.
HCFD = 1 Hold mode was released by a signal change at port RD.
5.15.5 Event Flag (EVF, EVFD)
The event flag is organized as a 8-bit binary register (EVF.0 to EVF.7) and EVFD. It is set by hardware
and reset by CLR EVF,#I, CLR EVFD instructions or the interrupt occurrence. The bit descriptions are
as follows:
R/W
R/W
R/W
EVF
0
1

Note: R/W means read/write.
EVF.0 = 1 Overflow from divider 0 occurred.
EVF.1 = 1 Underflow from timer 0 occurred.
EVF.2 = 1 Signal change at port RC occurred.
EVF.3 = 1 Falling edge signal at port P1.2 (/INT0) occurred.
EVF.4 = 1 Overflow from divider 1 occurred.
EVF.5 = 1 Serial I/O occurred.
EVF.6 = 1 Falling edge signal at port P1.3 (/INT1) occurred.
EVF.7 = 1 Underflow from Timer 1 occurred.
EVFD = 1 Signal change at port RD occurred.
5.16 Reset Function
The W742E/C813 is reset either by a power-on reset or by using the external RES pin. The initial
state of the W742E/C813 after the reset function is executed is described below.
