16.3.4.1 EMG Protection Circuit
16.3.4.2 EMG Release Register (PMDnEMGREL)
circuit is activated when the EMG input becomes low. The EMG protection circuit offers an emergency
stop mechanism: when the EMG input is asserted (H → L), all six port outputs are immediately disabled
(depending on the EMGCR<EMGMD> setting) and an EMG interrupt (INTEMG) is generated.
EMGCR<EMGMD> can be set to output a control signal that sets external output ports to high impedance
in case of an emergency.
tool break occurs, external output ports can be set to high impedance through the setting of the PORTMD
register.
EMGSTA<EMGST> indicates that the EMG protection circuit is active. In this state, EMG protection can
be released by setting all the port output lines inactive (MDOUT[10:8][5:0]) and then setting
EMGCR<EMGRS> to 1.
then clear EMGCR<EMGEN> to 0. (These three instructions must be executed consecutively.) While the
EMG protection input is low, any attempt to release the EMG protection state is ignored. Before setting
EMGCR<EMGRS> to 1 to release EMG protection, make sure that EMGST<EMGI> is high.

EMG protection is set through the EMG Control Register (EMGCR). A read value of 1 in
of the EMGREL register.
The EMG and OVV protection functions can be disabled by setting 5A and A5 in this order to bits 7 to 0
When disabling these functions, EMGCR<EMGEN> and OVVCR<OVVEN> must be cleared to 0.
After reset, the EMG function is enabled but EMG pin is configured as a normal port.
Therefore, as the EMG protection might be valid, release the EMG protection by the following
procedure at the initial sequence.
If the EMG protection is to be disabled, continue the following procedure.
* This register is used for both the EMG and OVV functions.
① Selects EMG function by PxFC register.
② Reads PMDnEMGSTA<EMGI> to confirm it as “1”.
③ Sets PMDnMDOUT<10:8、5:0> to ”0” to make all ports in-active (“L” output).
④ Releases EMG protection by setting PMDnEMGCR<EMGRS> to ”1”.
⑤ Writes the key codes to PMDnEMGREL. (In order of 0x5A and 0xA5)
⑥ Sets PMDnEMGCR<EMGEN> to ”0” to disable the EMG protection.
