Figure 9. Hold Mode and Interrupt Operation Flow Chart
Hold Mode Operation
All operations of the
μ
C cease in hold mode except for oscillator , timer, divider and LCD driver . The
μ
C enters hold mode
while the HOLD instruction is executed. The hold mode can be released by one of seven ways which are timer 0
underflow, timer 1 underflow, divider overflow, speech playing finished, melody playing finished, RC port pin state
changed and RD port pin state changed. Before the device enters the hold mode, the HEF, PEF, and IEF flags must be
set to define the hold mode release conditions. For more details, refer to the instruction sets and Figure 9.
Event Flag Register (EVF with SRP=05H)
The event flag is organized as an 8-bit binary EVF0 to EVF7 that EVFL and EVFH registers store EVF.0 ~ EVF.3 and
