Hold Mode Release Enable Flag (HEF)
The hold mode release enable flag is organized as an 8-bit binary register (HEF.0 to HEF.7). The
HEF is used to control the hold mode release conditions. It is controlled by the MOV HEF, #I
instruction. The bit descriptions are as follows:
w
0
1
2
HEF
w

w
w
3
4
5

7
w

Note: W means write only.
HEF.0 = 1 Overflow from the Divider 0 causes Hold mode to be released.
HEF.1 = 1 Underflow from Timer 0 causes Hold mode to be released.
HEF.2 = 1 Signal change at port RC causes Hold mode to be released.
HEF.3 is reserved.
HEF.4 = 1 Falling edge signal at the
INT
pin causes Hold mode to be released.
HEF.5 = 1 The serial port received completely causes Hold mode to be released.
HEF.6 = 1 The serial port transmitted completely causes Hold mode to be released.
HEF.7 = 1 Underflow from Timer 1 causes Hold mode to be released.
Hold Mode Release Condition Flag (HCF)
The hold mode release condition flag is organized as a 8-bit binary register (HCF0 to HCF7). It
indicates by which interrupt source the hold mode has been released, and is loaded by hardware. The
HCF can be read out by the MOVA R, HCFL
and MOVA R, HCFH instructions. When any of the HCF
bits is "1," the hold mode will be released and the HOLD instruction is invalid. The HCF can be reset
by the CLR EVF or MOV HEF,#I (HEF = 0) instructions. When EVF and HEF have been reset, the
corresponding bit of HCF is reset simultaneously. The bit descriptions are as follows:
R

Note: R means read only.
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 is reserved.
HCF.4 = 1 Hold mode was released by a falling edge signal at the
INT
pin
HCF.5 = 1 Hold mode was released by underflow from the timer 1
HCF.6 = 1 Hold mode was released by the serial port received completely.
HCF.7 = 1 Hold mode was released by the serial port transmitted completely.
